Girls, have you ever humiliated a boy?

Have you ever done anything to publicly humiliate a boy (maybe because he'd done something to annoy you, or maybe you were just being mean !) To give an example, you might have found out something embarrassing about him and then told other girls about it.

If you've ever done anything like this, what were the reasons, what did you do, and how did it affect the boy in question?
