What Does 'Kwsdrftgy Fujiko LP (Keyboard-Mash Scream)' Mean?

Produced by a very specific, reproducible keyboard-input accident: when a Japanese IME (input method editor) is active and someone mashes the keyboard in a burst of intense emotion without properly converting to kana/kanji, the raw romaji keystrokes come out as this exact garbled string, because of the physical layout of a standard keyboard. It became a recognizable 2channel-era artifact in its own right — reposted and recognized purely by its shape — precisely because it isn't a written word at all, but a lexicalized accident of Japanese text input.
