look up any word, like eiffel tower:
The act of shitting out a car window onto another persons car. Usually at desperate times. * farting excessively indicates you may have to carmud*

WARNING : Can Be Very Messy And Disgusting!
Dude, I had to take a massive shit while in traffic, so i rolled down the window, stuck my bare ass out, and projected carmud all over the car behind me!
