Usage
What does weirdo mean? A weirdo is a person who behaves in ways that are considered odd or unconventional. Weirdo is based on the adjective weird, which most commonly means strange, odd, peculiar, or bizarre. Weirdo is very informal. It can be used both negatively as an insult and positively as a compliment, depending on how you feel about someone else’s weird behavior. Much less commonly, weirdo can be used as an informal term for a person considered a dangerous psychopath. Example: My dog keeps licking the wall—what a weirdo!
