fackter
A person who acts like they're better than you but still messes with your head. Basically a f***ing pain in the a** who has a say in your life.
My boss is a fackter. He says I'm lazy, but he's the one who never finishes his own work.
My cousin is a fackter. She always ruins my plans but still thinks she's the best.
My teacher is a fackter. She gives me bad grades but still talks to my mom like she's my friend.
