combination of "fucking" and "hilarious". the cool and discreet way to say "fucking hilarious," and if your g-rents ask what it means, you can say "oh...just funny and hilarious combined"

an incredulously great word intertwining the words f-ing and 'hilarious', utilized when something is so amazingly funny that you are enveloped in laughter and cannot find the strength within you to cease the laughing.

When something is so funny that your rolling on the floor laughing or peeing your pants dont matter how old you are you can be 80 and peeing your pants or rolling on the floor laughing its gotta be filarious .
ROLLING ON THE FLOOR LAUGHING WHILE PISSING YOUR SELF . ONE DAY ME AND MY FRIENDS WERE TALKING AND I THOUGHT OF SUMTHING FUNNY AND I PEED MY PANTS THAT WAS FILARIOUS.
