Costco Guys

Origin

The Costco Guys are a father-son duo from Boca Raton, Florida: A.J. Befumo (Andrew Befumo Jr., born January 16, 1976) and his young son ‘Big Justice’ (Eric Justice Befumo, born April 8, 2013). The family, previously from Colts Neck Township, New Jersey, began posting high-energy reviews filmed inside Costco warehouses, and their first clip went viral in January 2024. Their signature ‘Costco Guys’ self-introduction video piled up more than 47 million views by mid-2024. A.J. has said the trademark ‘boom’ dates back to his own youth — shouting it after middle-school home runs and, later, after quarterback sacks in high-school football.

What it means and how it is used

The act runs on a homemade rating system: a great Costco find earns a ‘boom,’ a bad one gets a ‘doom,’ and the pair often host ‘Boom or Doom’ segments where guests judge two items. ‘We bring the boom’ is the signature catchphrase, ‘boom’ works as a freestanding unit of excitement, and ‘two-piece’ is one of Big Justice’s recurring signature phrases. The audio quickly detached from groceries and became reusable hype for sports highlights, food, and reaction content of every kind. Fans slap a ‘six boom’ or ‘ten boom’ verdict on anything from a great meal to a game-winning play, treating the scale as a universal applause meter.

How it spread

The duo gained roughly 3 million TikTok followers through 2024 and signed with the talent-management company Night in May 2024. Child creator ‘the Rizzler’ (Christian Joseph) began appearing with them around June 2024 and became a regular collaborator. Their hip-hop single ‘We Bring the Boom’ — released in early July 2024 over a beat widely compared to Run-DMC’s ‘It’s Tricky’ — became one of the summer’s viral songs, drawing well over 14 million views on TikTok. An October 1, 2024 remix added verses from the Rizzler, Jersey Joe, Cousin Angelo, and Grandma Lulu and pulled in more than 2 million views in a day. Rolling Stone profiled them as the father-son act behind a ‘song of the summer.’

Notable examples and variations

• ‘Boom or Doom’ crossovers with Bleacher Report rating NFL and MLB moments.
• A performance on ‘The Tonight Show Starring Jimmy Fallon’ and an appearance on an AEW All Out pre-show.
• Collaborations with the viral Savannah Bananas baseball team.
• The Rizzler-featuring ‘We Bring the Boom’ remix and a widening cast of family and friends.

Legacy and cultural impact

The Costco Guys became a defining example of 2024’s affectionate embrace of ‘cringe’ — loud, earnest, family-friendly brainrot that parents and kids quoted alike. What started as bulk-groceries content turned into a music act, a live-appearance draw, and a genuine crossover into sports and late-night television. By late 2024 the pair were a fixture of the year’s meme calendar — proof that sincere enthusiasm, not irony, could power one of the internet’s biggest breakouts.
