a comment or series of comments that are at the same time both funny and infuriating because of how ridiculous they are.

John told me that he had never actually seen a lion, and then spent half an hour trying to tell me they don't exist. some of the things he said were kilarious.

Something so hilarious, that it kills you the second you see/hear it. Not actually murder, you just almost "die laughing."

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'"
