What is duh?

duh is an informal interjection used to express obviousness, stupidity, or incredulity. It's often used sarcastically when someone states something glaringly apparent. You might say "duh" after someone makes a self-evident statement, like saying water is wet, implying the statement was unnecessary or foolish.

The term can be considered rude or dismissive, as it implies the speaker views the other person's statement or action as lacking intelligence or insight.
