A person or persons who most commonly wear baggy jeans or wear knee length raggy denim shorts. They usually wear baggy t-shirts. Sometimes they go in moshpits, (sometimes they don't because they don't want a broken arm!) It's a myth that a moshers worst enemy are townies because I'm a mosher and I have more townie friends than mosher friends! Usually into rock, metal music!
