M.I.S.I.C.H.N.O.

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."

Jesus Christ - "God damn it!"
