Rainbro

A homosexual male, who still maintains all the qualities of true bro's. The best example is Neil Patrick Harris.

Friend 1- Wait, so you're saying Esteban played basketball today? I thought he was gay.

Friend 2- He is. He's just an ultimate rainbro.

Rainbro

When two guys cum in each other's hands, then high-five, letting the cum rain on them.

Me and my boyfriend, Joey, decided to get extreme with our relationship. We jacked off together, catching each other's cum, then high-fived while listening to Metallica. We then created the Rainbro.

He's not gay, he's just supportive of his friends; a true rainbro.

Rainbro

One of the guys who is a total bro (usually on a sports team) who takes the "acting gay" thing to far and actually engages in legit homosexual activity with his fellow rainbros.

Dude1: Hey man did you see those football players touchin each other's dicks in the showers?
Dude2: Yea dude they are a bunch of rainbros.
