Silly in the Underpants  

State of being in absolute "pimpish" synergy. Mind, body, and underpants coming together in an ultimate state of carma leading to divine intervention and infallability. Most often associated in situations dealing with the opposite sex.

Iceman: Dude, did you see the funbags on that dime piece?

Johnny: I am so silly in the underpants Ice. Permission for fly by.
