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.

head on a swivel 

To be constantly moving your head left and right so that you do not miss anything approaching you from a blind spot

Mandy had her head on a swivel as she rode her bicycle in downtown traffic in order to avoid getting hit by a car.

perch and swivel 

A profane invitation whereas the one doing the inviting is flipping a most vulgar bird to illustrate how the invitee might wish to sit on it while spinning.

I have a most brilliant suggestion for you my dear: why don’t you just perch and swivel on this?

Swivel Rant

Usually seen on blogs and other comment sites, a swivel rant is little more than an angry run down of points/issues/people you wish to tell to go swivel.

"Did you get a response to your proposal on your blog?"

"Yeah, but nothing constructive, just a swivel rant"

Swiveltexting 

When one sits on a swiveling stool and text messages.

Another name for fucking the dog.

Rob spent the day swiveltexting instead of doing his job.
