What Does "oneul saengpa eodiseohae?" (오늘 생파 어디서해?) Mean in Korean?

This expression is highly casual and would only be used between close friends, family members, or peers who are already familiar with each other and comfortable using informal speech. Using it with someone older, of higher status, or a stranger would be considered rude or overly familiar. The use of '생파' (saengpa), an abbreviation of '생일 파티' (saengil pati), further emphasizes its casual and youthful tone, though it's widely understood across ages in informal contexts. It's a quick, direct way to ask for practical information about an expected event.
