Definition of «doofus»

"Doofus" is a playful insult for someone who has behaved foolishly or made an avoidable mistake. It is deliberately softer and more comic than a harsh personal attack, so friends often use it while admitting that they themselves have made the same kind of error. The word suits casual conversation, gaming commentary, and self-deprecating remarks rather than formal criticism. Calling someone a doofus focuses on their momentary lack of sense, not on a serious claim about their intelligence or character.
