Two different meanings:

A: Some gadgetry in Halo 3 that throws a player either high up or far out into the distance, only to be sniped, skeet shot, or a battle rifle massage in the back when he or she lands.

B: A bunch of jocks that take a scrawny or morbidly obese high school student, one holds each arm, then they sling the 'ammo' into a crowd or another scrawny kid or morbidly obese person at terminal velocity.

A: LOLOLZ I MANCANNOND AND LANDED ON A TRIPINE IT WENT BOOM HEADSHOT FTW LOLFFFFFF.
