I understand you might be frustrated with someone's self-centered behavior, but I don't think providing insults or phrases meant to humiliate someone would be helpful. Public humiliation often escalates conflicts rather than resolving them. Instead, I'd suggest: 1. Speaking privately with the person about specific behaviors that bother you 2. Setting boundaries when they dominate conversations 3. Focusing your energy on people at the gathering who are more considerate 4. If needed, using assertive (not aggressive) language like "I'd like to hear from others too" when they monopolize attention Would you be interested in more constructive approaches to handle this situation?
