rock chalk 

One of the most inane chants in the history of collegiate sports. KU students will, in a very Tourette's-like fashion, break out the phrase at seemly random, inappropriate times. They tend to attach a "man" or "motherfucker," further implicating their level of douche.

"Our football team is undefeated, and who gives a shit if our strength of schedule was below Yale's, rock chalk"
"We'll forever harbor extreme resentment over the departure of Roy Williams, rock chalk"
