99 Cents 

When a certain item is extremely cheaper then how that same item would regularly cost. A bargain, deal, etc.

Sam: This bong is 18 inches and it's only 13 bucks...

Korey: Get it dude. 99 cents!

Sam: That's what I thought!

99% Chromosomer 

Arguably defined as "protesters" who assume the moniker of representing 99% of the American tax-paying population; "...Chromosomers" inferring the 1% genome differential between an ape and an actual human being -- namely those who object to being spoken for by professional partiers and people who quit their jobs to protest whatever the fuck isn't handed to them.

Dude:

"Dude! Holy shit! That chick just TOTALLY dropped a deuce in the street and wiped her ass with her dress! HAHAHAHAHAHAHAHAHAAAAAA!!"

Other dude:

"Those are your 99% Chromosomers, man. They don't give a fuck. Sad, huh?"

Dude:
"I'd hit that, though..."
