Indeed, the term refers to performing cunilingus on a menstruating female, often followed by orally swapping semen and blood/other secretions. NOTHING to do with homosexuals.
When a guy gives head to a girl while she is having her period, and gets all the blood in his mouth. And a girl gives a guy head, and gets cum in her mouth.
Now when the guy/girl has blood/cum in their mouth, they kisseachother.
Basically, the guy gives the girl a mouthpiece whilst she's subscribing to the monthly rags. She simultaneously gives him head till he shoots his load in her mouth. Once they have an adequate mouthful of eachothers bodily fluids, both participants rear up their heads and enjoy the different sensations that tickles their taste buds in a passionate kiss.
As it was the only way I was ever gonna get head off that frigid bitch I had to grit my teeth, cover my eyes and boldy go where no man has gone before.

Rainbow Kiss
Performing 69 while a woman is on her period. The man ejaculates in the woman's mouth and the two kiss, the menstrual blood and semen mixing to form a beautiful rainbow of colour.
During a girls menstration the male performs oral sex and takes a mouthful of her blood. While the male has blood in his mouth the girl performs oral sex and takes a load. They then exchange a passionate kiss with their body secretions in their mouth through a kiss
When you have sex, when the gurl iz on her period. Both partners suck the gurls blood and the boys cum into their mouths, and then they french kiss then swallow the remenants.
Katy : Me and Jim performed a rainbow kiss last night!
Jill : Did the cum taste nasty?
