hilarian 

My sister came up with this word to describe me when she was about eight years old. It is a portmanteau combining "hilarious" and "comedian." It is used sarcastically conveying the idea that "although you think you're funny, you're not."

Dude: Jack be not nimble; Jack be not quick; Jack couldn't jump over that there candlestick.
Bro: Hilarious, dude.
Dude: I'm a poet, I knows it.
Bro: Yeah, you're a real hilarian.

Mentally Hilarious 

A 'better' alternative to using the word 'crazy' or 'insane' to someone. Or just a fun way to call someone crazy. Also, 'mentally jolly' can be used. From the Family Guy episode 'The Fat Guy Strangler'.

"Dr, is my brother really insane?"
"Mrs Griffin, we don't use the word 'insane', we prefer the term 'mentally hilarious'"

Hilaristurbing 

"Hilaristurbing" (adj) used to describe something that is both HILARious and dISTURBING.

It's origin is from an online story written by Alexandra Erin called "Tales of MU".

In the story - an adventurous nymph named Amaranth describes her attempt to teach a horse to count with the intent to avoid her deity's prohibition against lying with unintelligent beings. Chapter 60 - Leather

“Hey, I just discovered a new adjective,” Steff said. “‘Hilaristurbing’.” She turned to me. “I think Amaranth has exited the dungeon, hon…”
