when something is generally undesirable, dirty, ghetto or just plain crap.
alternatively, "tut" can be used as a precursor to dut (when something has not quite reached the point of being dut)
dick: hey jane, look at that guy eating out of the garbage!
jane: man, that is just plain DUT!
Dut can also be joined to words to explain just how dut something is. For example, dutstang, dutberry, kentucky fried dut, Los Angeldut etc...
