It might be a combination of the Spanish words "matraca" and "quillosa" but even then, the meaning is unclear.
Possible Interpretations:
* "Matraca" can mean a "rattle" or "chatterbox" in Spanish.
* "Quillosa" might be a made-up word related to "quill," which refers to a bird's feather used for writing.
Without more context, it's impossible to determine the intended meaning of "matraquillosa."
If you provide more context, I can try to help you understand what it might mean.
