Used for someone who does/says stupid shit. For use instead of saying fag or idiot or moron. You use this making the person think you called them Gabriel. Then coming back and letting it be known that they're "Gay Bro"
After saying a stupid joke that No one laughs at:
Me: Wow, that wasn't funny gaybro
Johnny: My name's not Gabriel.
Me: I know, but you're fucking GAAAY BRO!!
