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.
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'"
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
12 step recovery jargon referring to someone new who talks about how great life is, now that they'resober. Usually meaning that the person is out of touch with reality.
The new guy seems pretty happy for a dude who has no job, no money and no family. He must be on a pink cloud.
