It's the word Scwing with a "Kah" sound at the beginning.
Used to identify a woman who is not only obscenely smokin' hot, but gives you a boner so fast and hard that it hits your zipper with the force of a bullet and causes a lot of pain.
Dudeski 1: Dude, did you see that girl at the mall yesterday?

Dudeski 2: Yeah, my dick Ka-Schinged so hard I think I ripped off some skin. I even shouted "Ka-Schwing"!

Dudeski 1: So that's why you fell over. And it explains the groin cast.
