look up any word, like donkey punch:
 
1.
A mental headbutt. Such a concentrated amount of mental force that it feels like you just received a headbutt.
(Person 1): You better not piss me off or I'll mindbutt you!

(Person 2): That's bullshit you can't even OW what the fuck was that?

(Person 1): MIND. BUTT. BITCH.
