And as I said before, if people are that confused by "end line, base line," they have bigger problems.

I agree you should say the correct things, but this is the vernacular of the game that most players, coaches and fans are going to use. It is OK IMO to speak their language. You start correcting everyone because they did not use the perfect term, you will confuse them even more in many minor situations.
