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
