Much like the Houdini, The Sunny Kofax is accomplished while performing the act of coitus (doggy style) with a sexual counterpart, and feigning sexual climax, waiting for the partner to turn around, and shouting "FASTBALL!" and throwing the ejaculate mess into their face. Achieving maximum satisfaction for the Kofaxer.
Wendy: Kevin, what's wrong with your eye?
Kevin: My boyfriend gave me sonny kofax last night and it got infected.
Henry: Maya, how come you're walking so funny today?
Maya: I'm not sure, but i sure did get a mean sonny kofax this morning.
