"A boss in a game, in which you hit them multiple times with attacks but the corresponding sound is a 'tink' and little to no damage. As coined by Game Grumps."
In a video game, when there is a single, subtle weak point on an enemy and attacking the majority of his body results in a futile "tink" sound.
"Why are you such a bad man?"
"I ju-he's-he's tinky!"
"Are you saying that because when you shoot him--"
"Yeah"
"--and the things hit him--"
"He goes *tink*
"--he makes a *tink* noise"
"He goes *tink*! He's a tinky-ass motherfucker!"
"This bitch is tinky!"
