mallpunk
See also: mallcore. Someone who dresses "punk"(usually all black, with studs and chains, died black hair) but listens to crappy bands like Simple Plan, New Found Glory, and other Mallcore bands. This person usually has no idea why they dress this way other than it goes against "the man" and is the way they saw a REAL punker dress. Also thinks they are punk because they listen to Green Day, and usually has no idea who Clash, Ramones, Sex Pistols, or Black Flag are. Hangs out at the mall, where they only shop at Hot Topic.
You guys see that Mallpunk over there? I bet he likes to bump the new Good Charlotte record in his mom's minivan.
