When playing online video games, usually FPSs, some players may call you "garbage". By telling you this, they are either implying that you
suck at the game, or that you're using a cheap way to win. When they
mean you're using a cheap way to win, they're usually just saying that in attempt to make it your fault that they themselves
suck a salty nut at the game.
"Dude you
got killed while trying the noob combo, you'
re garbage."
"DUDE! You killed me with the noob combo! You'
re garbage!"
