I just kind of made it up one day and i've loveed that insult ever since. It can be a total nerd ass or an athlete that thinks hes the **** but hes really nothing but a tool. Also in websters dictionary see Mormon, which is probably my basis for the joke.
(not that all mormon are inheritally Gangle fucks, cause i have some mormon friens, but don't they just scream "hey im a gangle ****" when they knock on your door. cause i don't listen to the stuff they're saying i'm just thinking man this guy is a total gangle ****.
Does that clear anything up. sorry i know its hard to explain new insults. By the way did you see that clip TKD vs MT 2. TKD ownage at its best.
