1. A guy that's way too fast having sex, a premature ejaculator.

2. Something you say to a girl after having unsatisfying sex, often adding 'It'll last longer.'

This works on so many levels, the receiver of the insult will probably not even know it's an insult!

(noun)
1. A pimp in which the women he consorts with are less than desirable.
2. A man that has sex with ugly and/or fat girls on a regular basis.
