The word stunod can be used in three different ways, just like the word, stupid. For example, "That was such a stunod thing to do." Or, "How can you be so stunod?"(the second way of putting stunod in a sentence is not commonly used). And lastly "You're such a stunod" which is the most commonly used way of saying the word. The definition of stunod is someone/something/an unreasonable event, that was stupid. When you say stunod, it is just like saying stupid but you can use the word in more sentences and it adds a bit of spice to your insult/joke. Only the most elite people use the word, stunod.
