Slang referring to someone, or a group of people who are dirty, ghetto, and smokes
cigarettes and/or do dirty drugs like speed.
Comes from the combination of the words "ratchet", "pack", "dart" (being slang for
cigarettes) and "gang".
Does not refer to just anyone that smokes
cigarettes.
Every highschool has a ratchpack dartgang. Simply look to the smoker's corner for the dirtier looking kids who are always trying to bum smokes off of each other.
