Someone very gay. They play fortnite and stand little to no chance of mating. They usually spend their time getting really annoyed at people who join his minecraft server.
Guy: hey have you heard of Robtron255?
Girl: ew, the fortnite guy? he’s very gay!
Guy: I know right?!

*they laugh and skip off into the sunset due to their agreement that Robtron is very gay*
