A Chair usually infront of your gaming computer or infront of your tv that has the smell of a mixture of shit and slight piss, or the smell of swet due to the fact that you haven't been taking a shower and your ass literally lives on that chair and has grown it's roots on it.
Joe: Damn dude I play so much of call of duty I have a gaming chair now.
Bob: Ew that must smell like shit.
Joe: Yeah dude every time I take a shower and sit on it it smells like the ass of yesterday.
