A once mediocre economy car that has lost 80% of its value over the course of 4 years after being abused in the hands of its mentally challenged owner. Usually owned by either inbreds, crackheads, autist, Walmart DC workers, or ratchet side hoes. Usually has signs of damage all around the vehicle, and occasionally visual modifications applied in poor taste. Drivers hobbies include texting while driving on their iPhone that's at least 3 generations old, spilling Dunkin iced coffees on their stained seats, and blasting garbage music from their blown speakers.
Jenny: Hey Becky, did you ever get with that guy you met on tinder last night?

Becky: No, he came to pick me up to bring me back to his studio apt. so we could watch his free-trial of Netflix, but the passenger door handle of his Johnstown jalopy fell off so I couldn't go
