donnasaur 

The largest of the dinosaus, a bully and a fraud. There isn't any pictures of these arsehole dinosaus as they were Wiped out by the JATAS and no-one thought they were important enough to keep a record of their existence.

The donnasaur was not missed when expelled from the ice age.

dinasaur hed 

A meme from the Lostpedia forums. It started when someone made a very badly worded post asking if anyone had seen an "invisable dinasaur head" on a recent episode of Lost.

"Hed" was not actually said in the original post, but it ended up being morphed into that by other posters.

After a few pages, the thread became about taking quotes from normal posts on the Lostpedia forums and putting them over screencaps from Lost to make it appear like the characters are saying those things. The thread currently has 17,368 replies and counting.

The meme has even been recognized by the writers of the show after it was entered several times into a contest to decide the name of the finale episode of Lost. Damon and Carlton, the writers, joked about the name and called it the "worst finale codename".

Have you heard about the invisibul dinasaur hed on Lost?

Dorkasaurus 

An akward non social being often compared to a nerd, geek, dweeb, or a zip disk, also looks like a dinosaur or eats like one. Also considered a loner but in reality he could hang in any dinosaur or nerd crowd going unnoticed for up to 2 hours.

Boy 1: Dave your such a dorkasauras!

Dave: I'm sorry I am not up to your standards but dorkasaurus is hardly an insult at all.

Boy 2: I wish I was a dorkasaurus!!

Dave: Sit down, you'll never be that cool!

Boy 1: I don't get it...

dinkasaurus 

When someone is being a huge dick

You're out at a sporting event with like five of your buddies. Four of us have bought at least one or more rounds of beers for everyone. It's getting close to the end of the game, and there's that one dinkasaurus who hasn't bought any beers, yet has had no problems drinking all the free beer. He think's he's gotten away with being a cheap ass motherfucker, but everyone in the group has noticed.
You, talking to a couple in the group: "Hey, did you notice dickless didn't buy any beers?
Response: "Yeah... what a fucking dinkasaurus!"
