WTF mode is best stated, as being in a state of aggitation.
Where you just get so mad, and you flick the switch inside your head over to WTF Mode.
When in WTF mode you continously curse and then either hit someone or storm away.
ARGH! WHAT THE FUCK MAN!! YOU FUCKED MY FUCKING GIRLFRIEND! I CAN'T FUCKING BELIEVE YOU!
random person nearby: Yo, That guy was just in WTF Mode!
