A maneuver done on a highway in which one leaves a highway exit at the last possible minute by turning from the left lane on a two-lane highway, traversing the right lane, and immediately exiting.

That sonofabizznatch caused a 76 car pile-up because he decided to attempt a Douds without checking his right blind spot.
A miniature blue elephant with a megaphone that screams "Oosha booshka!" intermittently.

Fred: Dude, what the fuck is a doud?
Bob: Well, it is a miniature blue elephant with a microphone that screams "Oosha booshka!"
