methanical pancake swiveller 

A man with long, greasy hair, green teeth, baggy pinstripe trousers with braces and white plimmies. He sneaks around on farmland waiting for a cow to drop a pat. Slavering with excitement he drops his pants and swivels his bare arse on the still-warm bovine pancake whilst making high-pitched mooing sounds.

Its amazing how many methanical pancake swivellers you see on a sunny day.

Sniveler 

(noun) pronounced with a hard 'i' sound

1. A person who is conniving, and manipulates situations or people for their own benefit. Selfish. (insult)

2. Friendly jab at mutilative, often crafty behavior which is self serving, selfish.

3. Someone who pleads, whines, begs for something, which they don't deserve.

Originated in Pueblo, CO skateboard culture in the late 80's when an overeducated medical student attempted to insult a young skateboarder by calling him a sniveler (soft 'i' sound), a college dictionary word meaning a whiner, complainer, i.e. the Zorlac skateboard motto of the time 'Shut up and Skate'. Instead, a new word was born out of the manipulative behavior that was going on at the same time, likely borrowing money in a whining voice, maybe related to the use here of sniveller. Sniveler expanded in meaning to include behavior such as people stealing tips off tables to pay for their coffee, and any behavior that was self serving, or selfish. While an inside joke, term with skateboarders, it has since expanded coast to coast.

Okay, this isn't fair, you owe more money on the bill, don't be such a sniveler!

Dude, I don't like that guy, he is such a sniveler, always borrowing my stuff and never returning it. I think he sold that deck he borrowed.

He really should be paying rent for how long he has been crashing here, total sniveler.

Did you hear that guy running for office, what a sniveler.
