The exact original recording behind sorry I was pissin is not clearly documented, and it circulates mainly as an anonymous user upload on soundboards. It picked up traction because the phrase works as a universal, shameless excuse for disappearing mid-conversation. Streamers and meme pages use it as a comedic reply sound for late answers, AFK jokes and fake apology edits. Its staying power comes from relatability, since everyone has vanished for a bathroom break, and the crude honesty makes a simple apology instantly funnier than a polite one.
