Peepee poopoo is a long running piece of playground slang that survives online because it is simple, rhythmic and instantly understood as toilet humor. Short clips using the phrase circulate on soundboards and in meme edits where creators need a fast, immature joke without setting up a scene. This version, shared under the name peggyx, is used the same way, dropped into videos, streams and chat reactions as a standalone gag. Its appeal stays in that familiarity, letting an audience get the joke in seconds and move on.
