When someone acts faggoty, evasive, secretive, hostile and sneaky, they are a Fink. This is someone you don't want to associate with, but you don't want to fuck with either. Finks are known to be sly, deceptive, and powerful in certain ways. If there was a zombie apocalypse, a fink would be the smartest, strongest, faggiest zombie. If there were a zombie apocalypse however, you would want to find a human fink to be on your side so you don't get finked in the ass.
