slobber knocker

Made famous by JR (Jim Ross) of WWE. Used to describe a pro wrestling match that was bound to turn into a slugfest either due to the size and strength of the competitors, the level of heat generated by a feud leading up to the match, or both.

King (high-pitched excited tone): Now we got this Undertaker vs. Mankind Hell in a Cell Match!!

JR: King, that’s gonna be one hell of a slobber knocker and business is damn sure about to pick up. Sorry Mama.
