The phrase comes from everyday Polish slang, where pierdziec is a vulgar, childish way to talk about farting, which explains why the line spreads mostly as a joke among Polish speaking users online. Short spoken clips like this travel through group chats, gaming lobbies and meme pages because the meaning is clear even from the tone alone. It stays in rotation as a quick reaction for leaving, giving up or derailing a conversation, especially when a blunt and slightly gross punchline fits better than a polite goodbye or explanation.
