presumptuous

What does "presumptuous" mean?
To be presumptuous is to overstep the boundaries of what is appropriate or polite. Imagine someone who assumes they have a level of intimacy or authority they haven't actually earned, like a stranger trying to give you unsolicited life advice or a junior employee making a decision that belongs to the CEO. The word carries a sense of arrogance or audacity. It is usually used to criticize someone for being "bold in a bad way." While "confident" is a positive trait, "presumptuous" implies you have failed to read the room or respect social hierarchies.
