A word created through the mistyping of the words Hilarious Situations. First thought of in Port Huron Michigan in the year 2003. Can be used to describe people, places, things, events, or actions.
When we went to the concert and saw some drunk fool fall down the hill, that be hilations.
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'"
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.
