Is it bad to keep the cord plugged into my macbook after it is fully charged (green light coming on)?
 
Well if you don't expect, your battery cycles to skyrocket

In a sense, yes it is okay to leave it plugged in after it finishes charging. I might even say you're supposed to leave it plugged in
 
Why I am supposed to leave it charged in? Isn't overcharging things bad?
 
it automatically stops charging and runs of the power adapter once its full, and when theres a spike in power draw it will draw some from the battery intermittently. That's also why apple recommends you keep the battery in even when you are running off wall power
 
So I can technically keep it plugged in 24/7 and nothing would go wrong with the battery?
 
Yes, it's OK to leave it plugged in. You can't overcharge a Macbook battery. I kept mine plugged in and as a desktop for a year. I cycled the battery once a month. Now that I have a Mac Pro I use the Macbook as a laptop. My battery health is still 100%.
