A straight male who supports his gay friends' lifestyle.

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.

An extra softboy. Isn’t afraid to cry. Used the 🌈 emoji too often.
