What Is Son Saying

Son in his ghetto-ness explains a word in lay terms.
Hey son give me a W.I.S.S.!

Son: Alright the WISS for the day is "wanksta"
Son: It means "A "wanksta" is a very basic word meaning a person who acts/looks like a gangster or thug, but has never done anything gangster or thug-like besides acting or looking like one. It can be towards any race or ethnicity. The word does NOT imply a WHITE guy acting black. "

A Wiss is a portmanteau of Wimp and Piss...
The Word means a "Wimp who drinks Piss"...
This is the sort of albatross that gets hung around the neck of somebody who is bullied and then supposedly made up with by being bought a beer. Said beer, however, happens to have been dosed liberally with piss... This happens after the victim has been gotten drunk enough not to be able to prevent this from happening...
Ken was a Wiss the tough guys at the dock picked on regularly...
