flat monkey

It's a flat dick. It appears when you slam your nuts on a hard flat surface it's extremely painful but amusing to others.

Bro I got flat monkeyed the other day.

flat waffle

A females ass, as flat as a waffle with dimples all over, such as your girl.

Dylan: "wow your girl has such a flat waffle it's fucking nasty."

singing flat

Singing slightly off-note. When this happens in published work (e.g. YouTube videos, CD's, etc.) most of the audience doesn't even notice, but people with a strong sense of pitch (most notably, perfect pitch) can easily notice this.

"Mark made such an awesome cover, don't you agree?"
"What do you mean? He was singing flat the entire song."

Flatting out

To ‘flat out’ is to become so bowled over by a car’s looks, abilities, noise or general awesomeness that nothing short of passing out next to it can convey your feelings for said automobile.

Man Flats

Slip on shoes for men (not loafers, moccasins, or lace-less converse), generally patterned, lace-less, and are canvas or cotton topped. Man flats are commonly worn by scenesters and emos, and are a common accessory to skinny-pants. Although called man flats, man flats are also commonly found on the feet of girls and should still be referred to as man flats.

Eww, those man flats are so horrid!
