What Does “Dude” Mean?

At its core, dude is an informal term used to address someone, typically a man, but it's increasingly used for anyone regardless of gender. Think of it as a casual substitute for "friend," "guy," or even just a person's name. It originally referred to a man who was overly concerned with his appearance but has since evolved into a staple of American slang.

The feeling it conveys is almost always friendly and relaxed. It's a word that helps create a comfortable, informal atmosphere between speakers. While it can be used to express a range of emotions—from excitement to frustration—its primary function is to serve as a casual, all-purpose term of address.
