Schmekus 

A schmekus is someone who is being unbelievably douchey or stupid. This is used in a playful manner from friend to friend, and if anyone uses this as an insult they are being a Schmekus.

Person 1: Helen Keller went to town riding on a pony, stuck a feather in her cap and called it AHGBFFTHHAHAAAAAAHHHHH
Person 2: Stop being a Schmekus

Schmeckus 

Prepared hand-held food spilled from a wrapper while being eaten. (popularized by "Man v. Food" television host Adam Richman)

"Leaning forward against the counter on your elbows while eating an Italian beef sandwich means that schmeckus falling from the wrapper hits the counter or floor and not you."

Schmekis 

A driver (cellphone optional) who makes a really stupid move, or no move at all, forcing you to sit at a light, make a panic turn/lane change, slam on your brakes.

If that Schmekis! had been awake, we wouldn't still be sitting at this red light!
