dude with a pause after it. when something unbelievable happens you say this after like ten seconds, or when u cant believe someone did something stupid
1) Originally, “dude” meant a stuck up person who dressed overly well. It first emerged in the year 1883 in England.
2) Later it was used in the old west to mean a city person who moved to the west without actually know what he was doing. Synonymous with “city-slicker”
3) Later, in California, the term changed from these insults to a term meaning any male, human or otherwise. Sometimes it is used in reference to tom-girls. Now, it is often used for emphasis as well.
