Monorailed 

When a guy lays his hard penis on his belly and his girl slides her dripping wet pussy on top and glides along it like the Monorail at Disneyland.

OMG...Kelly Monorailed me last night it felt like I was on a ride to the happiest place on earth

monorailed 

Something that everyone seems to want, nobody agrees on how to do, and after many, many fruitless efforts simply cannot get done.

Damnit, I keep trying to get a water dispenser for the meeting areas at work... it must have been monorailed at the President's office, huh?

Springfield Monorail 

A public works project that is a huge waste of taxpayer money that turns out to be either a scam, a huge waste of money or both.
Comes from the Simpsons episode "Marge vs the Monorail" where Springfield spent all their money on a monorail only to have it fall apart on its maiden voyage.

The sky lift system cleveland put in fell apart after a week. That thing was a real Springfield Monorail.

big ass monorail

Origin: R. Crumb, 1960s-era underground comic artist. A bitch with an ass so big and bubbled that the top actually forms a shelf or seat, possibly large enough for an averaged-sized commuter to ride to work.

Steve: Yo, check out the booty!
Paul: She's the big ass monorail headin' downtown!

This is where the cat will lay with all four paws under his body and head laying on floor. It was so named for its resemblance to the mass transit system, the Monorail.
