Grudgemaster 

Someone who acts like a bitch towards everyone they know and tells them to get over it, but the moment someone is a bitch to them they get angry and never forgive you.

Timmy killed Sally’s dog with a pencil.

Sally cried. Timmy said “Your such a goddamn crybaby.”

Sally accidentally looked at Timmy without permission. Timmy had the Mexican drug cartel murder Sally’s family. Timmy then guilt tripped Sally for the rest of her life.

Timmy is the Grudgemaster.
