Unf is short for Unfortunately
We lost this match Unf :(
Unf i dont have time for this :(
A cultural incompetent individual born and raised in NE Michigan who never venture north of the Mackinaw Bridge or south of Saginaw. Quick to judge and feel threatened by newcomers who do not fit their dysfunctional, innate ideals and cannot identify another's lineage. If one has to be concerned they fall into this decayed social norm or offended, then you are most definitely a UNF.
A common question a UNF would ask, "Who are you from home?"
