A deviant sexual practice.
You start off by fucking a girl doggy style in the pussy, and then you switch hole. She will turn around and say wtf? and that's when you punch her in the face.

The word is a contraction of switch and punch. Swunch.
"I swunched that girl last night, it was awesome!"

"This chick is so swunchabe!"

"I just want to swunch her!"
