This is a short French meme clip built around the phrase 'Le caca a signé un CDI', running for just under six seconds. The joke pairs a crude subject with the very formal idea of signing a permanent employment contract, and that mismatch makes it feel silly, absurd and unexpectedly satisfying to hear in a chat.
