A store which makes people feel extremely self conscious if they are not anorexic (girls) or if they don't have six-packs (boys). Their clothes are skimpy and a "large" is a medium, a "medium" is a small, a "small" is a x-small and so on.
To put it simply: If you don't like stores where people stare at you for being more than skinny/buff and feel that $30 is too much to pay for a t-shirt, don't come here.
Skinny Girl #1: Oh my God, look at that loser over there. Can she even afford any of the stuff at Abercrombie & Fitch?
Skinny Girl #2: I know, right? She looks like she weighs more than 110 pounds, which is like SO overweight.
Normal Girl: looks around nervously and runs out of the store.
