Killarious 

Something so humourous that laughing becomes a danger to your life.

Signs of this may include severe choking due to lack of ability to breathe and rolling on the floor in an uncontrollable manner.

It was so killarious that he nearly suffocated!

Hillarious 

to be as funny or pleasing or to have high degree of humor as Hillary.

Early 21st century Native American: from Vietnam mixed German background ( from Greek hilaros 'cheerful' ) + ous. The sense ' exceedingly amusing ' dates from 2019.

Me: You're so Hillarious
Hillary: Haha that is so punny of you! ;)

Sillarious 

when something is silly and hilarious at the same time and you can't make up your mind on which word you want to say, this word is most likely to naturally come out of your mouth.

Tim: “You must like getting spanked Farley, I guess it runs in the family.”

Jillian: "ha! that was sillarious!

Kid: "SHUT UP!...SHUT UP!"
