Bae maintenance. The act of attending to your baes/boos/hoes.
When you're out with friends and take a FaceTime or long phone call with one of your current baes. *cj walks outside of the club/steak n shake to take phone call* Keisha says "ooooo CJ over there doing some Bae-tenance"

Another example : * you just got back home from hanging out with Bae #3 , and now you gotta. Text/call back Baes 1 and 2 *"dam now I gotta do some Bae-tenance"
