brown slut knuckle

This rare experience occurs when you are fisting a girl and your fist comes out brown, and you then realise that you were in her ass instead of her puss. It is usually bad news for all involved.

Mate1 - "Hey mate I was trying to fist a girl in the puss last night and I ended up with a bit of brown slut knuckle"

Mate2 - "nothing a bit of shower in a can wont fix"
