A mall rat is a creature that is overpopulating the malls across the nation, mostly on Saturday afternoons. These creatures are most known to be horny teenagers and early twenty-agers who can easily be spotted wearing slutty clothes that either has printed on them: Abercrombie, Hollister, American Eagle, or in fewer cases if it's a less fortunate mall rat, Aeropostale. These creatures think they are "cool" and will find someone to mate with by wearing such slutty clothes, but in reality, they are just wasting their life away walking around the damn mall all day long with nothing better to do. Also the younger mall rats (the vast majority of them) have their gullible parents walk into one of the clothing stores mentioned above with them so they can make them pay an arm and a leg for the overprice sluttly clothes sold there.
Mall rat 1: "Hey! what do you want to do this weekend?"
Mall rat 2: "I don't know. HEY! lets go to the mall!"
Mall rat 1: "Ok. Sounds fun! Maybe I can talk my mom into buying me those tight pre-ripped jeans from Abercrombie for $95, and then after that, we can walk around the mall all day there because we're cool!"
Mall rat 2: "OMG! that sounds like the perfect way to spend a Saturday!"
