Nakling
When you flirt with a girl, get her all hot and ready for sex, and then you tell her you're gay and walk off like a total jackass.
I got my crush all undressed and then I said 'I'm gay' and left her in shock.
I did a nakling on my date and she just stared at me like I was a monster.
My friend did a nakling and the girl ran out of the room crying.
