Redskulls 

Individuals who claim to be huge fans of comic book lore, but in reality know very little about the characters and their respective abilities, backgrounds, stories, etc. They are commonly known to brag about their comic book "knowledge" (usually acquired solely from films and/or TV shows), and are quick to condescend to those who question their familiarity of the subject. Their habits include attending midnight premieres of comic book movies and wearing superhero T-shirts out in public to display their active involvement in "geek culture".

*Thanos pops up during the end-credits scene of The Avengers*

Comic book geek: "Woah, no way! It's Thanos!"

Redskulls sitting a row back: "Uh...pretty sure that's Red Skull bro."

Radickulus 

Pronounced ra-dick-you-lus. Considerable force is used when saying this word, but it is not to be shouted. Something of absolute incomprehendible absurdity. Usually associated with positive connotations, but can also be used negatively. It's origins are believed to be a joining of ridiculous and radical.

A character in a video game uses an attack that causes the game to crash.
"That attack was radickulus."
