What does it mean to be stuck up?

Being "stuck up" refers to a person who is arrogant, snobbish, or overly self-important, often displaying disdain for others they perceive as socially inferior. This attitude can manifest in behaviors such as being condescending, aloof, or dismissive. Stuck-up individuals may prioritize their social status or material possessions, leading to a lack of genuine connection with others. Overall, it reflects an inflated sense of self-worth that alienates rather than engages.
