Sistating 

To spend time with your sista (or sister) via phone. Other Variations: Auto-sistating-when both sista's are on the phone; Manual-sistating-sistating while attempting to drive a manual transmission vehicle; Personal-sistating-spending time together in person; Self-sistating-just thinking about your sista.

While I was on the highway, I thought I was sistating with Kathryn, but I was really auto-sistating because she was in the car on the way home.
