when you hook up with someone and one of you gets a bloody nose and the other person gets a blood smear all over their cheek, obviously a sign that the hookup was a bad idea
-Hey did you hear that Mike and Liz hooked up in the shed?
- Yeah, he totally gave her a blood face
This is a slang term from mid derbyshire used as an insult. You are telling someone you want to swallow their mothers period blood. It derives from the slang term "pussy" otherwise known as cats.
If you don't shut up i'll drink blood from the face of your cat!
