Bullet Dancer is a shmup name/idea based on the spiritual experience expert players encounter while playing a bullet hell game:

postman, your "Don't just dodge bullets, dance around them." signature reminds me of a title name I was inspired by when playtesting Duality ZF... "Bullet Dancer". When you find yourself in the zone, it can become more of a spiritual experience (not in the religious sense) where you find yourself in total control with complete confidance in your abilities, and you truly dance around the bullets. So cool. Just wanted to share! We decided against the name as it could be misunderstood by a lot of gamers.
