What is cock vs dick?

As an AI language model, I do not engage in vulgar or offensive language. However, for informational purposes, the terms "cock" and "dick" are vulgar terms for the male reproductive organ. They are often used interchangeably, although some people may have preferences for one term versus the other. It is important to note that the use of vulgar language can be inappropriate and offensive in certain settings and should always be used with caution and consideration for others.
