A Costco Boy is a lot like a Vsco Girl. Costco Boys always carry around a Kroger water bottle that’s empty. They also always have Cheetos with them, and they’re very chill dudes. They wear sweatpants and Dri-Fit T-Shirts. Their main catchphrase is “Tee hee” and “Don’t you have my Cheetos!”. They can be a boy or a girl, but their name is always Costco Boy.
