2.
1. Someone so irredeemably idiotic that it is safe to assume that they derive pleasure from slashing cocks... possibly with a blade of some sort, we just don't know.
2. A general term for an annoying or stupid person.
3. A generic insult, can easily deployed as it rolls off the tongue like water off a Goretex duck.

(Commonly accredited to the legendary Bruce)
