A pinger is a defining euphamism for a superlative pork stonker which, if hit sharply with a ball pein hammer, would make a pinging noise like sharply rapping a tuning fork with a drumstick.
A term used by the rainbow six siege EU community to describe players from the middle east who don't play on asian servers but play on EU servers and have a high ping. This usually results in a stupid and aggressive playstyle as they have a ping advantage in quick peeks and such. Usually found around the Platinum 3 rank and have very big egos even if they are the worst players in the game.
player 1: fucking pingers player 2: i know right, why can't they play on asian severs
