crank me up 

A Notre Dame student body cheer that is mostly reserved for football games and pep rallies. The cheer was a highly unnecessary addition to the ND cheer repertoire in the 2008 football season. It was first introduced to the student body at the first pep rally, before the San Diego State season opening game.

"Jimmy Clausen, you suck. Go get a haircut. Where the hell is Brady? What the hell are the freshman cheering? Crank me up? What is that?!"
"New cheer, it was introduced at the pep rally."
"Pep rally? People still go to those?"
"You're an upperclassman, aren't you?"
"Bingo."
