Haiglarious 

The act when a boss, or higher ranked, employer at a company shares a joke or funny tale at an attempt to amuse their workers when in reality said joke or tale is in fact dull and only amusing in the employers eyes. Commonly followed with a tag line: "you had to have been there". Mostly used by co-workers to point out bland senses of humor.

Boy, that joke was 'haiglarious'...

Hey, what was that 'haiglarious' story you told earlier?

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'"

halarious

The way far too many people spell "hilarious." It is definitely one of the most popular misspelled words in the english laguage. "Halarious" is how most people pronounce "Hilarious" in every day speech. This is the root of the word.

An IM conversation:
-------------------------

Joe: "Dood thatz halarious"

Grant: "No dude, it's your typing that's hilarious."

When a person laughs hard enough they pull both wrists to their chest and open their mouth while rocking back and fourth but stay in their own personal space. Similar to a velocilaughter.

That girl was laughing so hard she was doing the hilariousaurus rex
