Polyfag, someone who dates multiple people, whether together or separately or cheats on their original partner for someone else, but doesn't break up with their original partner and instead dates both people.
"Gabe pretty much is a Polyfag, he has two boyfriends and he cheats on them with a chick."

After the school found out Jason cheated on his girlfriend with 4 other chicks in a Subway restroom, he was permanently labeled a Polyfag for the rest of the year.
