Loser guys with bad hair and clothes.
Gweedos are underweight guys with really bad hair such as mullets or any other type of hair that makes you think wtf. They are usually seen wearing too tight, too faded, tapered jeans, tucked in with a t-shirt with the name of a beer on it. They are often times spoted with their class jackets, from 1988.
