Who are The Costco Guys AJ and Big Justice? Father-son TikTok duo and Jimmy Fallon show guests

COSTCO guys brought the ‘boom’ to The Tonight Show Starring Jimmy Fallon for their first late-night appearance.

The chat show host welcomed internet sensations, A.J, Big Justice, and The Rizzler to his stage to get their signature review on some sweet treats.

The duo’s first viral post was a TikTok shared on December 28th, 2022 with their review of Sally Slices’ New Jersey Pizzeria.

Collaborators

The Rizzler often collaborates with the Costco Guys and he featured with the duo as a guest on The Tonight Show, hosted by Jimmy Fallon – aired on October 29, 2024.

The Rizzler’s videos on the app have scored over 19 million likes and he’s just as popular on Instagram with 556,000 followers.

The young influencer, whose real name is Christian Joseph, gained a mass following on the social media after wearing a Black Panther costume in a comedic video posted on TikTok.

The seven-year-old is best known for doing the “rizz” face which has since become another TikTok trend.

His signature “rizz” face involves him raising one eyebrow, dropping the other, sucking in his cheeks and pouts lips slightly.

The move is finished with a smooth stroke of his chin as if deep in thought.

Other TikTok users have tried to copy the expression, with hilarious results.

The Rizzler tried to teach Jimmy how to do it on The Tonight Show, and it wasn’t overly successful.

Other popular faces who appear alongside the Costco Guys page are family members Angelo, and Big Justice’s sister Ashley.
