👉 Ultrafrivolous, in the context of psychology and sociology, is a concept that refers to individuals who are highly self-centered and overly obsessed with their own happiness, often at the expense of others. This can manifest as an extreme focus on material possessions, excessive socializing, or a lack of interest in communal activities. The term was coined by sociologist and psychologist Daniel Kahneman in his book "Thinking, Fast and Slow."
