Get the Jackmug. Jack is a nice guy who can sometimes be the worlds biggest douche bag when it comes to everything. When he isn't being a douche bag(1 in million chance, possibly never) he can be a really top-class guy who's fun to be with and is great at playing with friends on games. Play any game with him and he will kill you and he will enjoy it, making you feel annoyed and want to stab him in every part of his body.
Guy: WTF! why did you kill me?
Jack: you might have been a traitor
Guy: but I wasn't
Jack: That's what a traitor would say
Guy; Stop being such a Jack
Jack; But I am Jack
Guy: WTF! why did you kill me?
Jack: you might have been a traitor
Guy: but I wasn't
Jack: That's what a traitor would say
Guy; Stop being such a Jack
Jack; But I am Jack
