It actually should be the transliteration for 'guitar' in Chinese pronunciation, so the user's identity or major hobbies possibly have something connected with guitars. Maybe music plays a critical role in their life, serving as entertainment, stress relief, or artistic pursuits. They may play guitar for leisure time activities, participate in bands for stage performance, etc. Also, they could just adore music and love the sound made by the guitar, wishing to showcase their interest directly.
