These are alternate spellings/pronunciations to the already defined term "Creepersaurus rex". They refer to a very creepy person who exhibits monstrously creepy behavior that they remind you of a creepy dinosaur. The spellings and pronunciations may vary by person due to sociocultural, economic, geographical, and several other factors.
Person 1: That Facebook stalker was totally a creeposaurus. I got the heebie-jeebies!
Person 2: Me too! But, I personally say/spell it creepasaurus rex, but I'm glad we agree on something.
Person 1: Trueee. It does come from Creepersaurus rex, anyway...
Person 2: Creepo, creepa, creeper.... All of the describe this weird ass person!
Person 1: Yes, a Creeposaurus/creepasaurus rex indeed!
A person who is beyond creepy, like a creepy dinosaur (such as a T-rex). They are very strange, weird, bizarre, uncomfortable, and are usually very much unaware of it. A Creepersaurus rex will exhibit inappropriate behavior, such as stalking, demonstrating mental breakdowns on social media, or worse.
Teacher: This former student of ours posted pictures of my colleague on her Facebook cover photos without his knowing and she totally came off as a Creepersaurus rex. Stay clear of her.
Colleague: Omg... Yikes! The zoomed in photo sure didn't make it any less creepy, huh...
An act of coitus where both participants cover each other in spray cheese. Following this, they must lay the crackers on each other in a scale pattern turning each other into a Ritz-Cheezasaurus.
Both participants must try their best to not damage the crackers while "saving their species from extinction." At the end of the act, both participants will come to a mutual consensus on which of the two get to survive. The one that survives, betrays the other and must eat the cracker scales and cheese off the other participant without using their hands.
Hey bro, I was with this chick that wanted to try the Ritz-cheezasaurus last night. I was the survivor. Would recommend. Except now I have to get a new bedspread.
