A generic term describing some sort of weird, creepy, stupid, or just plain annoying action or saying of someone else. It is derived from the last name of an odd member of a high school debate team and, like many things in the debate community, is only used when other debaters are present. The best effect is achieved when said with a derisive tone. While the original meaning had a somewhat dirty connotation, the current interpretation applies to any action deemed unacceptable or gross.
Riggsy: "I will eat your children and sleep on their bones!!!"
Mr. Awesome: "Dude, quit sprinking!"
"Why is he eating paper?"
"It's ok, he's just sprinking."
