The true definition of a flounder is a shapeless woman who has neither breasts nor an ass. She is thinly shaped up and down much like the fish.
The flounder originally thought she was cute until she discovered that she lacked any sexual organ that would catch the eye of the opposite sex.

A flounder is the act of pushing one's buttocks together while standing and defecating, resulting in two brown smears forming on each of the buttocks. These smears each are flat, brown, and circular, much like the shape of the flounder fish. Floundering is preferably done in the shower, so that one can simply rinse the flounders off when done, and no one has to know about it.
Matt told me about how he gave himself a flounder last night, and went into way too much detail. Gross!

Craig is such a flounder! All he does every day at work is sit in his office with his feet propped up on the desk reading the Wall Street Journal.

One who Flounds. Term used for a certain type of basketball player. Strengths are quickness, driving, and shooting the ball moderately well. Playing style is unorthodox. Shoots layups with 2 hands. Tends to be lanky in stature. Weaknesses are, well, everything else. Prone to being rejected, out rebounded, and shooting bricks. Can get the job done.

Parker: "Got 'em..."

(v.) the act of placing your hand between someones legs from behind, and flopping your hand under their balls like a flounder, but not actually touching their balls, that would be gay unless "no homo" is called. Usually results in a startled reaction from the individual it is applied to.

Flounder, Floundered, Floundering
Person 1: "Dude why does Marlon look so bummed?"
Person 2: "Ohh, i just floundered him and he was so surprised that he pooped a little and it dripped down his legs onto his sock. Those are new socks."
Person 1: "Ohh that sucks, at least he gives good LJ's and can move silently through the night"
