Premium rainbow kiss

When a rainbow kiss isn’t exciting enough so you insert skittles into the menstrating female then swap the semen blood and skittles by kissing.

I’m bored with a normal rainbow kiss, do you want to try an premium rainbow kiss instead? I have the skittles

steaming raincoat

A euphemism for a condom with ejaculate in it; a used condom

You have to be careful not to leave your steaming raincoat somewhere the dog can get to it.

Black Rainbow Troll

A PC Karen who trolls urban dictionary and ruins good things including the REAL definition of black rainbow.

I went to look up the definition of Black Rainbow but all I see is this unseasoned definition. It must have been the PC Black Rainbow Troll red flaging definitions on urban lingo again. Typical Black Rainbow Troll.

fuzzy rainbows

Used in the Stage countdown before the first set starts at a Billy Strings concert.

(15 minutes 'till 8pm they announce: 15 minutes 'till fuzzy rainbows. At 5 minutes until fuzzy rainbows the crowd grew noticably excited.)
