downasaur 

When someone is being an extremely large downer, and is complaining, therefore ruining everyone elses good time as well. Can be elaborated on by adding statements such as "Stop eating all the fun" and "Why do you have to eat all the good-time that exists in this room?"
Can also happen when the person is not saying anything but just acting extremely mopey and not contributing to the conversation.

Girl: "This party is so lame. I'm so hungry and the music here sucks. We should leave. Aren't you hungry? Don't you think tonight was crappy?"
Guy: "God stop being such a downasaur and eating everyone else's good time!"

Pownasaurus 

Typically a 12 year-old boy, whose balls have no quite dropped yet. Playing COD or Halo, screaming at the top of his squeaky annoying voice whenever he feels he has accomplished something of importance. Not to be confused with the Pownasaurus-Rex . A middle-aged balding version of the pre-teen Pownasaurus. Who, despite the dropping of balls, still sucks at life.

"AHHH DOOOD! I am totally like the POWNASAURUS right now! I definately just jumped into that vehicle, damn right, POWNASAURUS on the prowl!!!"
"Man...STFU you squeaky voiced beeeyyotch!"

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...
