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'"

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

unintentionally hilarious 

Adjective: description of any expression, statement or definition which, although originally intended in earnest, results adversely in humorous disdain.

"Wendy's attempt to explain how her underwear ended up in the frat house rec room was unintentionally hilarious."

Hillious 

Terrain/land that is not mountainous, but has elevation. A specific area of land that gains in elevation and then drops, although not as much as a mountainous area would.

The land area below the Rocky Mountains is hillious.

We took a hike that was rather steep and hillious.
