Overview
A.J. & Big Justice is the public-facing name of American father-and-son entertainers Andrew "A.J." Befumo Jr. and Eric Justice Befumo. The pair are also widely known online as the Costco Guys, a nickname derived from their highly recognizable videos filmed around visits to Costco warehouse stores. Their content combines family-vlog elements, food and product reactions, physical comedy, exaggerated catchphrases, recurring characters, and a deliberately theatrical presentation built around the contrasting ideas of a product being a "boom" or a "doom." Andrew Befumo had an earlier career in professional wrestling. During his college years and through the 1990s and early 2000s, he worked for independent promotions in New Jersey under the ring name "the American Powerchild Eric Justice." He later became a mortgage-business regional manager and created TikTok content under the character Mortgage Muscles, using short-form video to explain aspects of the housing market. His social-media work changed direction after his son Eric began appearing in the videos. The father-and-son format became the foundation of the A.J. & Big Justice identity. The duo's early joint video was recorded in December 2023. Their breakthrough came in January 2024 with a video showing them shopping for meatballs for Eric's mother at Costco. In March 2024, they explicitly adopted the Costco Guys identity, and their warehouse-store videos began reaching a large audience. Their format generally involves reviewing or reacting to Costco products, with enthusiastic responses described as a "boom" and unfavorable ones labeled a "doom." The simple vocabulary, expressive delivery, and family participation made the clips highly repeatable and suitable for memes, remixes, and audience participation. By spring 2024, the account had surpassed one million TikTok followers, and by later in the year the duo had accumulated more than two million followers on the platform. Their reach expanded beyond TikTok to YouTube, Snapchat, Cameo, podcasts, and other social platforms. In May 2024, they signed with the talent-management company Night and became full-time content creators. Other members of the Befumo family, including Erika and Ashley, also appeared in their content. Christian Joseph, a child creator known online as the Rizzler, became an important recurring collaborator and participated in several public appearances and musical releases. Music became a significant extension of the brand in 2024. In July, A.J. & Big Justice released the hip-hop novelty single "We Bring the Boom," whose lyrics and presentation drew directly on their video vocabulary. The track generated substantial online attention and was followed by remixes, including one featuring the Rizzler. The duo also appeared on podcasts and on The Tonight Show Starring Jimmy Fallon, while a Saturday Night Live sketch parodied their social-media format. These appearances moved the brand from a platform-native meme into broader American popular culture. Professional wrestling remains another defining part of the identity. In late 2024, A.J. returned to wrestling for All Elite Wrestling, facing Q. T. Marshall at Full Gear with Big Justice in his corner. A.J. later wrestled at AEW Revolution alongside Orange Cassidy and Mark Briscoe, again with Big Justice and the Rizzler involved. At the post-event media scrum, A.J. said that he, Big Justice, and the Rizzler had signed AEW contracts and would continue appearing for the promotion, with A.J. wrestling intermittently. The group subsequently appeared at additional AEW events, including All In: Texas and Full Gear. As a result, A.J. & Big Justice operates less like a conventional consumer-goods brand and more like a character-led entertainment property spanning social media, music, live appearances, family content, and wrestling.
History
Andrew "A.J." Befumo Jr. developed the performance background that later shaped A.J. & Big Justice through independent professional wrestling in New Jersey. During college and through the 1990s and early 2000s, he wrestled under the name "the American Powerchild Eric Justice." He later worked in the mortgage industry and created TikTok videos as Mortgage Muscles, a character used to explain housing-market topics. Befumo also established a family-vlogging channel, All Befumo'd Up!, when his son Eric was three years old. The family eventually relocated from Colts Neck Township, New Jersey, to Boca Raton, Florida. Eric, born in 2013 and named in reference to his father's wrestling persona, began appearing more prominently in A.J.'s short-form videos after asking to participate. Their first recorded joint video in December 2023 showed Eric introducing his father while A.J. ate a hamburger. The decisive turning point came in January 2024, when the pair posted a video connected to a Costco shopping trip for meatballs intended for Eric's mother. The clip's success led them to build a recurring format around visits to the warehouse retailer. In March, they began calling themselves the Costco Guys. Their videos featured product reactions, exaggerated physicality, and a binary rating language: favorable products received a boom, while disappointing ones received a doom. This format gave viewers a compact set of phrases and gestures that could be repeated across clips and adapted into memes. The audience grew rapidly during the first half of 2024. By June, the duo had exceeded one million TikTok followers and had become the subject of widely circulated online memes. Their presence expanded to YouTube, Snapchat, Cameo, podcasts, and other social platforms. In May, they signed with Night and transitioned into full-time content creation. Family members Erika and Ashley began appearing, as did Christian Joseph, the child creator known as the Rizzler. The Rizzler became a recurring collaborator in videos, public appearances, and musical projects. The brand broadened from social video into music in July 2024 with the release of We Bring the Boom. The song drew its language and concept from the duo's established videos and generated enough online interest to support several remixes, including one with the Rizzler. A.J. & Big Justice also appeared on The Tonight Show Starring Jimmy Fallon and on podcasts, while Saturday Night Live incorporated a parody of their TikTok persona into a sketch. By this period, the duo had accumulated more than two million TikTok followers. Wrestling provided a second major expansion path. In October 2024, A.J. announced that he would face Q. T. Marshall at AEW Full Gear at Newark's Prudential Center. He won the match on November 23, with Big Justice in his corner. The event was followed by an injury to A.J.'s foot sustained while preparing for the match. The family nevertheless continued appearing for AEW, including as hosts or on-air personalities at Christmas Collision. On January 3, 2025, A.J. announced another AEW appearance at Revolution. At the March 9 event, he teamed with Orange Cassidy and Mark Briscoe against Johnny TV and MxM Collection, with Big Justice and the Rizzler in his corner. During the post-event media scrum, A.J. stated that he, Big Justice, and the Rizzler had signed AEW contracts and would continue making appearances, while A.J. would wrestle selectively. The group later appeared at All In: Texas in an eight-man tag team match. A.J. and Marshall also used the Boom & Doom name in a later Full Gear match. Through these developments, A.J. & Big Justice evolved from a viral family-video identity into a cross-platform entertainment property combining social content, music, celebrity appearances, and professional wrestling.
