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

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.

The Rainbow Bridge 

The rainbow bridge is a part of heaven that is crossed by a beloved pet and their owner every day, your pets go to a lovely valley where everything is happy and they are healthy and as soon as you pass there is a lovely reunion and you and your fur baby will cross the bridge, never to be parted again.

Old person; “I will see you after I cross the rainbow bridge with Oreo.”
Teen; “Grandpa you’re delusional.”
Old person; “Just wait and see.”
