look up any word, like thot:
whipped cream on shit
You sink a 40ft downhill putt for a quadruppe bogey (+4)while playing golf for a WCOS - whipped cream on shit.

The whipped cream is making the 40ft putt. The shit is the seven previous shots on the hole.

Abbreviation for "won't catch on". It's not going to become popular or gain wide-spread recognition.
Dylan: Hey, let's make up some random abbreviation!

You: Nah man, that WCO.
