Poor thing must need a hug.........
Edited to add: I think that your issues with these phrases comes from your misunderstanding of these phrases when used by other bassists. For example, "locking in with the drummer" doesn't necessarily mean "goosestepping" with the drummer. It does, however, mean being aware of the beat and hitting it at key points to keep the music flowing. How about "overplaying is bad?" Well, it is bad, but every song and every band is different, so "overplaying" is different in every song. Ever heard Wooten play with a band, not soloing? He knows how to reign in his playing in order to play basslines that fit the music. He doesn't double-thump every note just because he can.
Most bassists understand these types of generalizations and don't need them explained in detail every time they are used.
Yep, that would be my understanding of locking in too.
