When I say “tore up girl,” I’m assuming that you speak homosexual.  In case you don’t, being tore up is when one tells someone else how they looked, or more appropriately how they acted the night before. “Girl, you were TORE UP,” (i.e. you were drunk last night). “Girl, I got tore up last night,” (i.e. fucked—either literally, by a drug deal gone bad or beaten up). “Girl, stop shopping at the DI, you look tore up,” (i.e. cheap and/or disheveled). Essentially, if you’re a mess in any way, you can replace the adjective with “tore up.”
