Allegedly made of happy thoughts, dreams, chocolate unicorns, gumdrops, licorice sunsets, fuzzy gumdrop bears, and chocolate-covered gumdrop lands.

Rainbow

When a guy goes down on a girl on her period and keeps it in his mouth, then she goes down on him and keeps it in her mouth, then they kiss and mix it together (a.k.a. period blood and jism)

She's on the rag, so last night they made a rainbow.

Rainbow Lady

A lesbian. See also Rainbow Man and Rainbow Youth.

I thought that that girl was making out with a dude, but it turns out it was just a manish Rainbow Lady.
