fifth grade

A group of prepubescent kids who think they are 30 because they are on top of the elementary school and curse every sentence in public or in secret (cause elementary school is full of snitches) and try to be "swaggy" and also 5th grade patrols are the worst cause they think that just because they stand in a stupid hallway telling people to walk means that they are cooler then everyone else then report people for no reason and boss others around and try to act tough and lie about doing "manly" stuff like playing rated m games and owning a gun cause they think they are all grown up and big people even though they will go to middle school only to get shitstomped by 7th and 8th graders and get beaten up. To any 5th grader going to middle school, have fun getting raped (:

Fifth grade 1: Ah Fuck i hurt my fucking leg! man fuck this stupid blacktop! my fucking knee is hurting! ah shit my asshole shit shit shit!
Fifth grader 2: Damn your cool since you are fucking cursing like that is fucking cool as shit
Fifth grader 3: I am telling the teacher

fifty yarder

A girl that looks good from far, but far from good. Fifty yards away she looks like a dime, but as you get closer, you find that she's only a nickel. Maybe worse.

Damn, she's about a fifty yarder.

nifty fifty

A 50mm prime camera lens with an f-number of 1.8 or lower. The first lens to earn this nickname was the Canon EF 50mm f/1.8 II, introduced in 1991. Nifty fifties are cheap to buy, have sharp optics, and give amazing bokeh.

Yeah, I got a huge collection of zooms and wide angle lenses, but when all else fails, the nifty fifty always delivers.

Filthy Lava

The act of mixing pop rocks and soda in an anus that is pointing straight up in the air. 15 seconds of finger banging and one good fart creates an eruption.

"Damn! It has taken me one week to get that filthy lava off of my new boxers!"
