In a similar way the word evolution does not mean what it technically means when used in society in general. Therefore I think it is inadequate to call evolution simply a "change in frequency of hereditary traits in a breeding population from generation to generation" because it is quite different from what the ordinary lay person understands by the word evolution. So I think that it is time that evolutionists got over that fact and started using it the way it is used by the population in general.
Do you realize the massive amount of confusion that would take place if lay people were the ones who defined what scientists meant with their theories. Which lay people get to choose? How educated should they be? What would be the quorum number allowed for changing a definition?
What is the problem you have with any definition provided by scientists that allows them to communicate without confusion?
