How do you get rid of him?

Xenophilius Lovegood was known for his charming angel face but devilish personality in bed. If it wasn't for the rumours, you would have actually accepted a date with him. But, unfortunately for the poor Ravenclaw boy, you weren't that naive and didn't fall into his clutches. Normally he would try a few more times before passing to a new victim, but he simply couldn't get you out of his head, so he kept following you and talking your ears off until you gave in.
