A sudden outburst/exclamation which expresses one's disgust on someone particularly hideous, salty, sloppy, fugly, and other words of that nature.
In other words, its a natural reaction to the sudden sight of what you believe to be the most vile and disgusting woman/man. 'DOHHHHHHH!!!' is the next thing heard, coming out of your mouth, in pure disgust and even fright.
Pronounced the same manner as "door". Not to be mixed up with a "doe" sound.
