back boob

a fatty deposit on the back that hangs in such a way that it resembles a nippleless breast. May sometimes result from a bra that is too tight, causing temporary back boobs. Mostly seen on very fat women or men with manboobs.

"He's got a sick fetish--he goes to the nude beach just to look at back boobs."

Back Seat Gamer

Typically an individual whom excessively shouts at a friend who is trying to enjoy a game. Feeling that if the person isn't doing well in the game for lack of concentration. To the surroundings in the game, that by shouting in the person's ear on how to do it, the white noise being yelled at in the background will somehow improve concentration. Sometimes this can be beneficial while at other times you want to shove the controller down their throat and hang them from the ceiling with the cord.

"Dude you're not doing it right! Don't use that gun, use the other!"

"You better shut the hell up with the back seat gaming it's getting on my nerves..."

"Just do what I say all ready!"

"Seriously, stoping being a back seat gamer!"
