Backblast Area Clear 

a. a military cautionary statement, when one is firing the AT-4. One looks behind them, scanning for personnel 100 meters back in a 90 degree cone, once it is clear they yell backblast area clear and fire.

b. One looks behind them, and whether it's clear or not, yells BACKBLAST AREA CLEAR, and rips a loud veracious fart.

a. READY, BACKBLAST AREA CLEAR, FIRE FIRE FIRE

b. Hey Tom, backblast area clear, RIPPPPPP HAHAHAHA
