Multi-functional word to either describe a successfully executed joke or give that small nudge that a nearly laughter-worthy joke needs to push it into the cusp of laughter (
otherwise called an "assist"). This is also most powerful when used audibly to counter
the voices in
your head with something out of left field, so to speak.
Tom: "Those vagabonds camping
over there really live inTENTs lives..."
Crickets: "Hilario!"
The
Watchers (speaking in EMF): "sssssssss....EEEEEE.....EYEEEEEE..."
Vagabond: "Yeah, yeah; E-I-E-I-O, Mofo! Hilario!"
