Singapore Ski-Slope
A practical joke in which a person defacates into someones sink or tub, then hides the feces under a thick layer of shaving cream foam. The victim later rinses, or attempts to wipe away what they believe to be a pile of shaving cream, only to discover the suprise turd underneath.
I woke up after a sick party at my house and found a huge pile of shaving cream in my shower. When i turned the shower on and rinsed away the shaving cream there was a pile of sh*t underneath. I was totally Singapore Ski-Sloped!
Singapore Ski Slope
The act of taking a dump in someones sink, then covering it with shaving cream to hide it until someone (preferably the owner of the sink) uses the faucet.
I left a Singapore Ski Slope in Drunk Chris's sink last night. He was pretty pissed when he went to wash his hands this morning.
