Rainbow Rider 

n. A man who will pitch for, or get blown by, a gay man but maintains that he is 'straight'.

Girl 2: What?!
Girl 1: Yeah, I heard he bent that emo kid, Jake, over the concession stand last week.

End of the rainbow 

During sex, one partner fills his or her mouth with lucky charms, places a funnel in the other partner's asshole, proceeds to pour milk into the funnel, and drinks the milk out of the asshole. This results in an asshole milk-lucky charm concoction that is magically delicious and sexually arousing.

Man: You want to do an end of the rainbow?
Woman: Nah, the funnel doesn't fit anymore, it's too loose.

rainbow fist 

The rainbow fist is the movement which lets people show support to the lgbtq+ people of colour during this difficult time. People can show their support to these people by making the rainbow fist their profile picture across social media. Despite what you might hear, this in no way shape or form is the lgbtq+ community trying to take over the black lives matter movement.

Bob: “did you see Jeff changed his profile picture to a rainbow fist. So disgusting”
Jim: “you know the rainbow fist actually just shows support for the black lgbtq+ community.”
