Boom or Doom, or 5/5 Booms on the Boom Meter is a food rating system used by father and son TikTok duo A.J. and Big Justice, aka the Costco Guys.
The two use the system to rate food products in their recurring segment, “Boom or Doom.” If something receives the highest rating (a “boom”), it usually involves shouting “boom,” flexing a bicep, and an exploding graphic/emoji.
Boom or Doom became a popular meme in 2024 when users on TikTok and X started to question the accuracy of the rating system.
