A popular abbreviation for Hilarious, also a reference to Hilary Clinton. Usually used when the humor it is applied to is somewhat serious or not actually that funny. Though often used just because you feel like saying it......

Jenine: Wait isn't his mother an alcoholic?
Fred: Yea, isn't that so Hilary!
