Rainbow kisser

One that goes down on a female while she is on her period.

That nasty little rainbow kisser needs to wipe his mouth.

Dirty Rainbow Kisser

When a man ejaculates into his partner's asshole, then sucks it out, and proceeds to make-out with their partner.

I heard Dirty Rainbow Kissers are very popular at homosexual bars.
