knifeass

The feeling of a hot, serrated steak knife wedged up your asshole after a long, violent session of explosive diarrhea.

I have the worst knifeass today after drinking that McDonald's iced coffee.

Knifessed

To be caressed with a knife.

I gently knifessed her neck.

knife ass

The approximate 2 - 10 seconds of immense pain inside of a female's anus that comes and goes without warning. It feels like - more or less - a knife in one's ass.

Girl 1: *starts to wince in pain whilst squirming in chair*
Girl 2: Are you alright?!
Girl 1: *stops* Yeah, I just had a massive case of knife ass
Girl 2: Aw yeah I hate that
