An experimental type of magazine for use with assault rifle or submachine guns. It's shaped like 2 drum magazines clipped together. It's name is short for Cent-mag, as it holds 100 rounds of ammo. It is, however, rubbish, as it jams easily and weighs 3 times as a normal magazine.

A female who has many gay friends and who attracts them easily without even trying. However, a Fag Mag is not to be confused with a Fag Hag. Fag Mags have an average/high self-esteem, get frequent ass, do not rely on their gay friends for self-reassurance/affirmation, and are truly a gay man on the inside.
Gurl, you actually like yourself and you get so much ass. There's NO way you're a Fag Hag. Oh my god, you're totally a Fag Mag!
