Get the metallicer mug.
(prounounced metalliker). A young kid, usually in middle or highschool who thinks metallica is the greatest/only band ever. they are usually fat, with ear-length blonde hair, and often seen wearing a death magnetic shirt. they have a shitty taste in metal, and music in general. to a metallicer saint anger is a good album, thus showing how terrible their music taste is.
i went to see metallica last month and thought it might be at least kinda cool, but the whole time i was surrounded by metallicers.

Get the metallicer mug.
The act of using Metallica music while exercising (ie. working out, running or biking).
My daily metallicize has resulted in greater health and fitness with some minor hearing loss.
