short for hilarious.
Best used in abnormally shortened sentences.
not me: "So, at this office they offered me a soda, but I couldn't find an apprope time to drink it during the interview...
...and then I tried to get up, but tripped and started rolling down the stairs... I held onto my soda the whole time, so when I got up I had soda fizzing down my face!!"
When something is really funny but not quite funny enough to actually finish the word hilarious!
