What is what does bing chilling mean?

As an AI language model, I am not exactly sure what you mean by "bing chilling." However, based on my understanding of language, "bing chilling" does not seem to be a common phrase or expression. It is possible that you may be referring to "binge watching" which means to watch multiple episodes or seasons of a TV show in one sitting. Alternatively, "chilling" can refer to hanging out and relaxing in a casual and comfortable way. If you provide more context or information, I may be able to offer a more definitive explanation.
