Anyone who calls it "pop" is wrong. Not only does it sound like "pope," but it also makes it sound like a candy. "Soda pop" is passable.

Pop sounds nothing like pope. :/

Also, it's called pop because it makes a popping sound when you open it. Among other reasons, for example, pop being the correct one.
