Silent Mexican

When a person lays a silent but deadly fart at the same time someone else lays a loud fart and then proceeds to be blamed for the smelly fart. Very, very sneaky...

"Eww dude, that was nasty sounding" ...time goes by and everyone smells it... "BRO! That smells rank!" "..Wasn't my brew, mine don't smell like that"

It was a Silent Mexican

silent orgasm

An orgasm that is usually over the phone wherein one or both of the people on the phone orgasm without making any noise, usually because they are unconfortable with moaning or they think their partner is. You may experience this while participating in CPS, if not, you're a loser.

Joe: Dude, I was on the phone with Leann and she had a silent orgasm!
John: Really? How could you tell?
Joe: Well we were having CPS.
John: What is CPS?
Joe: You dipshit, look it up online.
John: Oo! Urban Dictionary dot com!
Joe: Yeah!

Silent Death-Striker 

A fart that is silent yet smells so bad

I let a Silent Death-Striker and casually walked away waiting for someone to walk in it's path.
