If you are in a red car and you pass another car, you are obligated to flash your headlights and yell "Kachow!" Or when you get into a car accident.

Also commonly referred to the classic catchphrase of the notorious "Lightning McQueen", kachow is a term that is used as a reference to when a man sneezes while taking a piss resulting in a "KACHOW". A kachow can only be avoided if the victim starts to force his piss stream to a higher PSI, or just holding in the sneeze.
Jim: Kachowwww!
Debbie: (walks into bathroom) What Jim?
Jim: I fucking sneezed while pissing, what else would it be?
Debbie: Kachow?
Jim: Fuck you Debbie, no one likes you.
