hilaritas 

Latin for cheerfulness, merriment, good humor

Guy #1: One time, when I was learning to drive, I was passing this guy on the left, and I accidentally put the car in "park" because I thought the "P" stood for "pass." That destroyed the transmission, immediately. At the time, I was doing 80-miles per hour on the freeway.

Guy #2: That's hilaritas.

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'"
