hiplarious 

the often amusing and bizarre combinations that hipsters create in fashion and cultural expression in an effort to stand apart and be 'hip', i.e.,

I found it totally hiplarious when my friend in the knit skater cap, kilt and crocs posted to his blog: naked unicyclists gathering in downtown Portland tonight.

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."

hilariousaurus rex

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
