YNF- "You're Not Funny"- the abbreviation posted to a social media site after someone makes a comment that is a failed attempt at comedy. Particularly good to use when the person is being passive aggressive OR is one of those people that comes out of the woodworks to grace the world with their "comedic genius".
Original Post: I'm so sick of work!
Comment 1: Oh really? Are you allergic to it? Is that why you are sick? You should get some meds for that.
