Basically, a piece of shit car. Usually cheap and/or broken down. Can be any size, make or model, but must (or should) be embarrassing to drive for some reason, such as when you bump the stereo all the plastic "effects" you have hot-glued to the exterior rattle, instantly betraying the cheapness of your bling.

A hoopty can be anything from a '78 Cadillac Brogham with the panels missing in front of the brake lights (but replaced on only one side with duct tape), to a fine purple two-year old Hyundai Elantra with three spinner hubcaps and a vanity plate that reads BBY GRL.

The term has also been used in certain circles as an insult to one's boy or girlfriend, as in scrub or hoochie mama.

In reference to cars: a vehicle in poor condition, often large, boatlike, and aided by duct tape or bungee cords. Comes in two flavors, White Trash and Black Ghetto. See also: hoopty mobile.

An enormous boat of a vehicle usually sported by ghetto queens or hick adolescents. Almost always appears in lime or puke green, although bondo is my favorite look. The lack of power steering makes this dinosaur turn like a son of a gun! When seen in ghetto queen fashion, add 8-12 kids piled in every square foot of this gentle giant.

Known for incredibly loud mufflers... if any.

A hoopty is beat-up, piece of shit car with a rusted-out body, a bad transmission, and an engine that only runs on sunny days!

An automobile which is most likely older than it's owner, but not old enough to be an eye-catching classic. Sporting a very dull paint job and Psoriasis-like rust spots, do-it-yourself tints with more bubbles than a freshly opened champaign bottle, a fully installed racing drivers seat (with the other seats left stock and most likely broken/torn), 5" plastic (or for more well-off hoopty drivers, aluminium) rims bought at a local Wal-Mart, and a rice-class muffler which belches out a large jet ski like sound, possibly so that the driver can attract the attention of blind chicks who otherwise can't be disguised by the hideousness of this vehicle.

cheap, beat up car - originated with a dude named hoopty in dc who ran a used car lot. lots of young dudes there got their first car (cheap and beat up) from hoopty

A busted-ass gas-guzzling automobile. A big, old, rusty motherfucker that resembles a loud rusty 4-wheeled version of the fuckin "Love Boat" coming around a corner. Usually occupied by a bunch of wannabe gangsta's.
