Longneckasaurus 

A person that likes to show off their expensive clothes and connections to celebrities but doesn’t actually talk at all.

Richard, one of the rich kids in my Government class, was being a Longneckasaurus after joining the video call and not talking at all.

Longneckasouris 

The Longneckasouris is the greatest creature that ever existed. The Longneckasouris species had a neck longer than a football field. They had their necks mistaken for dinosaur dildos when there fossils were dug up. The Longneckasouris survived the meteor because they could see it and went into a hole. Some species of the Longneckasouris still exist but it in human form. A human Longneckasouris is usually very tall and are depressed a lot too. The Longneckasouris has a Jesus of it and his name is Matt. Matt is a amazing Jesus for a amazing creature and is a really smart kid.

You are as high as a Longneckasouris.

Longbackasaurus

A female with very little or NO ASS whatsoever. Males will not be attracted to longbackasauruses at all.

Justin: "Man, Jess and Kyllie sure are Longbackasauruses."
Shayne: "Yeah, they have no ass at all!"
Grant: "Their jeans are baggy, that's how little ass they have"
