What Does "dapdaphae" (답답해) Mean in Korean?

This word is often used to express a sense of being suffocated or blocked, either literally (like in a stuffy room) or figuratively (when a situation is not progressing, or someone's behavior is illogical). It's a common expression of mild to moderate annoyance and is perfectly acceptable in casual conversation with friends, family, or even colleagues, as long as the context isn't overly formal. It conveys a strong sense of discomfort or exasperation.
