look up any word, like lemonparty:
One who listens to Nirvana, My Chemical Romance, The Used, Nickelback, Green Day, System of a Down, Atreyu, Korn, Incubus, Hawthorne Heights etc.

Mainstreamers listen to Mainstream Rock, know nothing about Music and usually think Nirvana are grunge, and My Chemical Romance are Emo.
Mainstreamers are quite fond of Nirvana.
