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.

Emma is such a twat block. Danny and I were supposed to be on a date, but she showed up and they talked the entire time!
