Short for "The Heat Is On," which is the name of a song by Glenn Most likely derived from the name of a short movie-type skit from Saturday Night Live, starring Ben Stiller, Jimmy Fallon, Horatio Sanz, and Will Ferrell as Glenn Frey. If you have not seen this skit, I highly recommend it -- it is absolutely hilarious!
M.I.S.I.C.H.N.O. - "Money Is Something I Currently Have None Of"
An acronym for all of our broke asses to use on the daily. Deriving from Wu-Tang and Method Mans infamous term C.R.E.A.M. (Cash Rules Everything Around Me), it is relatively opposite. While C.R.E.A.M. relates to the domination of money in our society and the wealthiness of others and maybe oneself, M.I.S.I.C.H.N.O. is a term describing how badly oneself is deprived of the much needed currency they need to survive, making life more difficult than it already is.
Jesus Christ - "Yo, Do you have any money I can borrow? I need to pay my life insurance payment by tomorrow."
Colonel Sanders - "Nah, M.I.S.I.C.H.N.O. brotha! My bad."
