This is a well-known browser security technique. In JavaScript, calling .toString() on a native browser function returns "function appendBuffer() { [native code] }". Calling it on a JavaScript function returns the actual source code. So if your appendBuffer has been monkey-patched, .toString() will betray you; it’ll return the attacker’s JavaScript source instead of the expected native code string.
Like many early internet memes, "so I herd u liek mudkips" doesn’t have a single, clean origin story. Some fans trace it back to MudKipClub, a DeviantArt group where the phrase was posted earnestly as an inside joke and invitation for other users to join the community. Others remember it spreading through 4chan, where it evolved into copypasta and became part of the platform's deeply chaotic, anything-goes humor.
