cambodian rainbow 

This is a sex position where the man is having sex with a woman suffering from a cold or flu, or other stomach problems. Shortly before the man ejaculates, he pulls out so the female can vomit on his dick.

My girl hasn't been feeling well all week, but I was really horny anyway. She ended up giving me a cambodian rainbow.
