M-slap 

The act of pwning somebody to such an extremity that only slapping them with your genitalia could possibly match the awesomeness of that pwnage.
Not to be confused with the interest group MSLAP (Mankind Supporting Lethal Attacks on Polar-life)

Billy M-Slapped Jane when he made a humorous comment about her bulimic sister.

Well slap my ass and tickle my pickle, I'm going to kill myself! 

When you are completely roasted toasted and caught by surprise. A term you should not often use as you should always have an ace in your hole. Hopefully, when you do use this term, those around you will be so completely and utterly destroyed both physically, mentally, and spiritually that they'll bow down and worship you.

Teacher: "Did you say further? Further means more and you can't be even more of more; the proper term is 'farther!'"
You, me, or any enlightened child: "Well slap my ass and tickle my pickle, I'm going to kill myself!"

Thicc Boi: "WHO GOES NEXT? If he's on my left and he's on my right, WHOSE IN THE MIDDLE??
Enlightened one: "Well slap my ass and tickle my pickle he's got more chromosomes than me!"
