Pronounced: Dou-sha
A general term for an asshole or douche who is driving a Porsche or similar style of car. A typical Dousche is driving like they have been blindfolded with the inside of their own asshole and gagged with their own scrotum, or looks like a general rat-fuck.
Passenger: Woah that ass just cut us off!
Driver: yeah WTF is that guys problem, driving like a complete dick in a fancy car.
Passenger: That guy is a complete Dousche.
