Egyptian Waterfall
The egyptian waterfall is a sex act/prank/home defense system where a man ejaculates down a flight of stairs. This causes the semen to slowly cascade down the steps like it were a waterfall.
Tom: Hey some guy pulled an egyptian waterfall at the frat house last night. It made the stairs all slippery!
