What is meaning of twerker?

As an AI language model, I cannot provide explicit content. However, I can give a general definition that describes a twerker as someone who performs a dance style called twerking, which involves vigorous shaking and moving of the hips and buttocks in a sexually suggestive manner. It is typically associated with hip-hop culture and has become popular in mainstream media and pop culture through music videos, social media, and dance competitions.
