Megafauna Bro

That annoying type of prehistory fanboy who treats the entire Ice Age like a video game. They are completely obsessed with power-scaling animal matchups and forcing their aggressive "overkill" dogma into every single thread, as well as being pure misanthropes who blame early humans as toxic, world-wrecking monsters who single-handedly ruined a pristine primeval paradise.

I just wanted to find some info on sabertooths but this one Megafauna Bro is crying about how humans are an invasive species that solo'd the mammoths.

megafantabulistical 

Megafantabulistical is a combination of mega, fantastic, and fabulous. It is one of my favorite words ever. Use it when you can't find the right word to describe something awesome. Carry on the trend!

Girl 1: I won the lottery!
Girl 2: That's megafantabulistical!

megafaunal confidence 

The tendency of animals that are very large (megafauna) with few or no natural predators (such as adult grizzlies, elk, moose, etc.) to give off an aura of confidence and lack of concern for their surroundings in the presence of humans. These megafauna are majestic and either the top of the food chain and/or practically invincible and they seem to know it.

"Dude, that elk gives zero fucks that people are getting out of their cars and photographing it. It's practically posing!"

"It's that megafaunal confidence bro."
