Golden Shower Feeling

Alright, listen up, smooth brain! So, the joke is about this 'golden shower', which you probably don't even know what that means, but it involves pee. And then, the punchline is 'pissed off'. Now, 'pissed off' means angry, right? But it also sounds like 'pissed off' as in, you know, the pee didn't get 'off' or wasn't 'pissed'. Get it? It's a play on words, you slowpoke!
