Appasaurus 

An older person addicted to using bunches of apps on his or her smart phone. Especially someone overly eager to share TMI about what apps they use.
An important distinction is the person doesn't just have the apps loaded on their phone, but uses them.

Dude: My grandpa tracks his diet, blood pressure, weight, exercise regimen, stock prices, medication schedule, all the family pictures, and tracks everyone's birthday with his smart phone, but doesn't have a single game on the darn thing.

Dudette: He sounds like a real appasaurus.
Dude: Yeah, but I can't complain too much. He just deposited $50 to my checking account, for my birthday, from his phone. Before he got the phone he never remembered my birthday.

Applesaurus 

Applesaurus (app-ul-sore-us) is a dinosaur entirely made of apples. Instead of bones like your common known t-rex, the applesaurus has "bones" of apple cores. They went extinct very quickly because they were eaten by other dinosaurs very quickly.
Believed to be an ankylosaurus and an apple combine.

There were no remains left of the applesaurus when the t-rex gobbled him up

Awkasaurus 

1. (noun) A situation that is not just an awkward situation, but an incredibly, uncomfortably awkward situation. Awkwardness to the extreme.

2. (also noun) The Awkasaurus is a creature that thrives off of extremely awkward situations. It's main goal is to make things more awkward. It does not have a roar, it instead only ever uses a mating call, which sounds like, "Rawgreramaassrkrrr!"

1. Sarah: "This is my associate, Mr. Osaka."

Gary: "Oh! Konichiwa!"

Alexander: "I'm from Nebraska..."

Sarah: *thinking* Ooh... That's a big ol' Awkasaurus.

2. *watching a movie with a friend*

*parents walk in on the one sex scene*

Awkasaurus: *lurking in the corner* "Rawgreramaassrkrrr!!"
