"xqqqme" has no standard meaning in Rubik's puzzles or any established puzzle notation. It appears to be a random character string.
If you encountered this in a specific context (e.g., a tutorial, algorithm sheet, scramble sequence, or code), please provide details:
With more context, I can determine if it's a typo, a specific notation (like commutator notation), or an inside joke/meme from a particular community.
