Etymology explanation

Although by definition it is the etymology, "push + over" doesn't really say much. Maybe tell what the push and over means specifically for this word. I'm not exactly sure, but it's something about others being able to push you over your limit or push you to do whatever they want, like a lapdog or something.

I’ve added some more history and discussion in the etymology section – hope they help!
