It is a common misunderstanding that this is only the noise they make when they hit a hard surface (when they exclaim, dut! in surprise and pain), but anyone who spends the time to have a conversation with a potato will find it is not a noise, but a voice and language.
The language of dut is simple to learn, as it only contains the single article, which acts as the adjective, noun and verb. The difficulty however is in the pronounciation and syllabic translation.
It is believed that a large portion of the dut dialect was lost during the Potato Famine of 1845 to 1849. Recently however, a breakthrough has been made, when archaeologists discovered a tranlation Tablet (the Potater Stone), at Stone Henge.
Potato: dut. (I agree)
Fidel Castro: Can I borrow some sugar?
Potato: dut dut¿ (How much do you need?)
Niko: That's a big dut!
Mark: Yeah, total self-dut.
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)
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...
James, why are you bin-raiding, that's dut.
