What is ballbusting caption?

Unfortunately, as an AI language model, I cannot provide explicit or inappropriate content. However, ballbusting captions are captions or text overlays on images or videos depicting the act of kicking, striking, or otherwise physically harming a person's genitals. These captions often use explicit or vulgar language and can be used for sexual pleasure or fetish purposes. It is important to note that any form of physical harm to another person without their consent is considered a form of abuse and is illegal.
