similiar to cock block, but from a female's point of view. It usually happens when the other girl has larger boobs.

Cock blocking between girls. When your friend is getting in the middle of you and a significant other or a one night stand. Basically stopping your love life. Tit blocking is used when your friend doesn't have anyone else and doesn't want to be the only single girl in the group, or when your drunk and ready to climb into the taxi with creepy Steve from HR.-example
Why are you tit blocking me?
