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"
Wow, you should have seen the latest episode of The Office - it was filarious.

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.
that was filarious!
