Greyjoy
A term used for trolling anyone named Theon who wishes to escape the unfortunate comparison with the Game of Thrones character, who is notorious for fucking prostitutes and ugly girls, feeling up his sister, and being a general douche.
Example:
Troll: "Wait, did you say your name was Theon, like from Game of Thrones?"
Theon: "FUUUUUUUUUUU"
Troll: "Haha how is your sister going, Greyjoy?"
