Any non-commercial, run-down, LOUD, American, low value, rear-wheel-drive
automobile/truck typically between 1970 ~ 1987 driven by skanky, trashy people who tear
around town like its the baddest ride ever. It's also common to yell: "SKANK-TANK!" (like "SLUG-BUG!") when such a person unintentionally proves that their
hunk of shit is nothing to prove.
