Pipeliner 

A pickup line that has a 70% chance of getting someone laid. Pipeliners are usually used by men since women don't normally have a hard time getting men to sleep with them.

Remember that chick from the 40/40 that was being kinda standoffish? yeah, so i served her a pipeliner and she can now tell you what my dick taste like?

Nookid: Hey, come here often?
Hot Chick: Not interested.
Nookid: I'm an upcoming rapper who is currently cutting a deal with def jam.
Hot Chick: I know this cool trick, whip out your dick and i'll show you.

Only applicable on the coolest fora ever:
A fucktard, but the word fuck has been replaced with the word pip, due to annoying censors.

"James Blunt is a piptard."

"You're such a fucking piptard."
