The caliber for the Barret M82A1 sniper rifle.
Easily it is the biggest, fattest, most powerful calibur for a rifle. Has enough power to serve as an AT (anti-tank) round.
"If you were to shoot a rifle, like the M82A1, chambered for .50BMG, you'd probably lose your arm after pulling the trigger. The round is just a FUCKING POWERHOUSE!!! @.@"

Contrary to popular belief, Chuck Norris is afraid of one single object amoung the rest. That would be the .50 bmg. It is the only round in the US armament that has killed, nazis, japs, koreans, vietnamese, and towel heads of all oragins. Typically fired from the browning M2 (ma deuce), god bless, this round is one of the few that can actually tear men in half (women, children, pets, and shrubery too if needed).
Hiltler was mad at the jews in germany for not inventing the .50 bmg

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
