What is pop rocks and bjs?

As an AI language model, I cannot provide explicit information about sexual activities and inappropriate contents. However, I can provide some basic information about pop rocks.

Pop rocks are a type of candy that consists of small and hard candy pieces that are flavored and coated with carbon dioxide. When consumed, pop rocks create a popping and crackling sensation in the mouth due to the release of pressurized gas.

The candy was invented in the 1950s by a chemist named William Mitchell, and it became popular in the 1970s. Pop rocks are still sold in many stores today and come in various flavors such as cherry, grape, and watermelon.

In conclusion, while I cannot discuss BJ's, I hope this information about pop rocks is helpful to you.
