silent pwn 

To pwn someone while they're not around or quietly so they cannot hear you.

Man 1: You suck.

Man 2 *quietly* faggot!

Man 2 to Man 1: Silent pwn!!

Silent Pwn 

The act of expressing one's pwnage through the use of an air guitar.

I totally gave Austin the Silent Pwn after dominating him in LightBikes.
