The “Costco Guys” meme, born from TikTok, exploded into mainstream media after Jimmy Fallon invited the duo A.J. and Big Justice, known for their quirky Costco-themed videos, onto The Tonight Show. The father-son pair, initially recognized for their upbeat store reviews and humorous take on the “Boom!” catchphrase, quickly became fan favorites. The pair review everything from Costco’s famous giant cookies to pizza slices, embodying an exaggerated enthusiasm for all things Costco.
During their recent appearance, Fallon seemed to struggle with the group’s boisterous and over-the-top energy. Clips of Fallon’s interactions with A.J., Big Justice, and fellow TikTok star “The Rizzler” left fans feeling uncomfortable, pointing out that Fallon’s typical high-spirited persona seemed to falter as he appeared uncharacteristically reserved. Some online reactions suggested that Fallon may have found their viral style challenging to engage with live.
The meme culture surrounding the “Costco Guys” fits into a broader trend of TikTok’s “We’re X, Of Course We Y” video style, where creators humorously categorize themselves with playful, exaggerated characteristics of various groups, from professionals to niche interests. A.J. and Big Justice have captivated audiences with this approach, especially those familiar with Costco’s unique offerings, bringing humor to everyday items.
The episode stirred even more interest in the duo’s videos and their “BOOM!” slogan. While Fallon’s response became its own topic of conversation, it has only fueled the popularity of the Costco Guys, showing the power of online culture to blend into traditional media platforms.
