A person who acts like or embodies the characteristics of a dude; someone who is fashionable or stylish in a dude-like manner.
From 'dude' plus the agent suffix '-er' (Old English '-ere'), which transforms verbs and nouns into words describing someone who performs or embodies a quality. 'Dudler' is less common than 'dudish' but follows standard English word formation patterns.
While 'dudler' isn't in most dictionaries, it represents how English speakers naturally create new words by adding '-er'—the same way we turned 'dude' into a verb ('to dude around') and then into agent nouns. Language is constantly being invented in real time, especially in casual speech.
