friend tease

Someone who is only friends with you, hoping for sex, but when they find out you don't want to bone them, they tell you there is no point in being friends and drop you like a hot rock.

We've been friends for three years, and I really value the friendship, but when he said he wanted to have sex, and I said no, he said, "Well, there's no point it being friends then." and he left! What a friend tease! :-(
