Overview

Were Costco Guys is a catchphrase video meme built around father-son TikTok pair A.J. and Big Justice Befumo (@a.j.befumo), who film themselves inside Costco warehouses hyping the store's food court items with call-and-response energy1. The signature line, 'We're Costco guys! Of course we...', slots into the earlier 'We're X, Of Course We Y' TikTok trend, but the Befumos' delivery, with Big Justice bellowing about chicken bakes and A.J. shouting about the new double chunk chocolate cookie, gave the format its recognizable rhythm3.

The meme lives on TikTok as short clips of the pair inside Costco holding food items, along with duet reactions, lip dubs, drawing recreations, and warped edits made by other creators5. Fans latched onto the wholesome dad and son dynamic paired with very specific Costco fandom, so the phrase quickly became shorthand online for enthusiastic warehouse-store energy.

On March 1st, 2024, TikTok account @a.j.befumo uploaded the first Were Costco Guys clip, in which Big Justice announces they are Costco guys who go shopping while eating a chicken bake and A.J. follows up about trying the new double chunk chocolate cookie1. Within roughly two weeks the post pulled about 20.3 million plays and 2.1 million likes, one of the account's breakout uploads3.

The clip piggybacked on the ongoing 'We're X, Of Course We Y' format already circulating on TikTok, but the Costco setting and the father-son delivery separated it from generic entries in that trend3.

How It Spread

Duet reactions hit almost immediately. On the same day the original went up, TikToker @cheeseballsinthehizhouse posted a duet that pulled over 3.5 million plays and 366,300 likes in two weeks2. A few days later, on March 4th, 2024, @wizardinatshirt filmed a live-action recreation inside an actual Costco store that racked up more than 2 million plays and 138,200 likes across eleven days4.

Warped and distressing edits followed. On March 3rd, 2024, @hexgd posted a version with darkened, morphed faces of A.J. and Big Justice that pulled over 3.3 million plays and 488,500 likes in thirteen days5. Drawing recreations arrived on March 10th, 2024, when @zork.honerd posted an illustrated take that hit 3.8 million plays and 486,400 likes in five days, followed by a similar piece from @funky_artist14 the same day6.

The Befumos then rolled out a companion clip on March 12th, 2024, in which A.J. answers repeated 'Hey A.J., what's that?' prompts with 'It's a double chunk chocolate cookie,' pulling more than 4.7 million plays and 457,600 likes in three days7. That cookie video started its own remix cycle, with edits like @yourthirdwheel's March 14th, 2024 post scoring 214,500 plays and 34,800 likes in under a day8.

How to Use This Meme

The template typically pairs the shouted 'We're Costco guys! Of course we...' line with any Costco-branded item or activity, usually filmed inside a warehouse aisle or food court. Common conventions include a hype call-and-response between two people, close-up shots of the food item, and matching the Befumos' loud, celebratory delivery1. Remix edits often warp the audio or visuals, or swap in different products for comedic effect5.
