The practice of strategically positioning oneself near a future point in the trajectory of a moving individual and timing one's flatulence to coincide with the individual's passing so that individual unknowingly passes through the nauseous gases causing dizziness, vomiting, rashes, temporary blindness, loss of appetite, disorientation, disgust, and general contempt. May also cause hilarity for the individual acting as the car wash. The act is similar to a car passing through a car wash but instead of getting clean, the victim usually just feels plain dirty.

Person 2: (Smiling) I'm car washing people and Bill threw up.
