a train wreck is basically a person whose life is a total disaster. train wrecks are typically promiscuous, party a lot, have multiple failed relationships, and indulge in activities such as illegal drugs, binge drinking, and chain smoking. these people can typically be found taking shots of whiskey and vodka and starting fights at bars, dancing drunk and awkwardly at clubs, smoking cigarettes, pot, or crack behind a gas station, driving drunk or high on your local highway, or hanging out at your local rehab center. if you know a train wreck and they've never been to rehab, advise them to go there. some famous examples of train wrecks include Lindsay Lohan, Charlie Sheen, Amanda Bynes, Shia LaBeouf, Britney Spears, Edward Furlong, Courtney Love, Tara Reid, Macaulay Culkin, and Paris Hilton.
