emosaurus 

The Emosaurus is a large orange dinosaur, with razor sharp metallic teeth. The Emosaurus spends its time roaming the world looking for Emo kids to eat for breakfast.

With its keen sense of smell, and ultra-sensitive Emo-detection hearing, It is quickly attracted to the smell of slitted wrists, and the sound of Simple Plan music.

The best way to avoid the Emosaurus is too stop living in the "Black Abyss." If you enjoy simple plan music, keep it low so that the Emosaurus understands you are not trying to make everyone else suffer.
-The Emosaurus ate the Emo kid for breakfast
-The Emosaurus makes the world a better place
-Go play with the Emosaur

Morosaurus

A semi aquatic monster/dinosaur that comes out and beats kids with anything available. If it be a pole or a canoe paddle, no one is safe. A morosaurus is very protective of his turf and will defend it at any cost. If you ever run across a morosaurus, the only way to escape is to yell "You won't" or "Square Up" as loud as you can. He will see it as a very offensive act and will scurry off into the wilderness.
That creature looked alot like a morosaurus!

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
