Noun; The unsatisfied and disappointed feeling that arises when a trip to the shooting range ends abruptly due to unforseen circumstances before a single shot is fired. Similar to Blue Balls, but involving guns, not ejaculation.
"My buddy and I loaded up about 1000 rounds of ammo last night, and when we got to the range today, it was closed due to vandalism. Now we have a serious case of blue mags..."

A new term for airsoft Hi-Cap magazines. High caps tend to rattle when you move with them due to a large reservoir that holds bbs. They are inferior to midcaps that hold less rounds but make no noise at all
I was sneaking around with my buddy but his fucking Maraca Mags alerted the enemies and they killed us, fuck hi-caps!
