A horrible song by a horrible "artist" (Soulja Boy) that talks about how some guy (Soulja Boy) whacks off onto a girls back when she's sleeping, and sticks a bed sheet to her back, and it sticks, hence SUPERMANN!
Soulja Boy: Crank dat soulja boy, superman dat ho.
Me (mark) : HOLY JESUS TITTY-FUCKING CHRIST, YOU BLOW BIG DONKEY COCK!
If someone has been provoked or wound up enough to get annoyed, respond angrily, or lose their cool, they have been cranked - or they are cranked. The word is then often employed on its own to crank them even further.
