When a man is trying to seduce a woman and he is getting some where and then another guy comes and makes him look bad. So then that guy gets the girl.
He was at a bar and saw this hot blonde and started impressing her but then a minor celebrity got in the way and cock blocked him.

Get the Banging the blocksmug. 
To do a female friend a favor by keeping her from getting it on with some unworthy male. The noblest thing to do for a friend.
My friend has gotten involved with an absolute pig! He's such a man-whore that the only right thing to do is to twat block her so she doesn't get some disease.
