I always called it dip. Chew is Levi Garrett and Redman, to me. I have noticed that people from outside of the Southeast called it chew, but that never made sense to me. Pop and soda have the same kind of regional slang. In the South, we call carbonated soft drinks such as Coca-Cola and Mtn Dew soda. In the Midwest, they call those drinks pop. Both terms make sense.
