look up any word, like meatspin:
A slippery heel is when you get up the urge to jack off in the morning(this isn't an easy task)first you blow a load in your tube sock then wear it on your foot the rest of the day.
Scott: dude, you need to buy some more socks, they're filthy.

Todd: No don't worry, I was just horny this morning, and now I got a slippery heel goin.
