When you are taking a class with Dr. Robertson, and you want to want to move on, but he is dragging out a quote, you are suffering from Post-Traumatic Robertson Syndrome.
My Post-Traumatic Robertson Syndrome (PTRS) is starting to kick in. We've been discussing the same quote from Kendi page 68 for the past 15 minutes!

On the Clubhouse app, a person constantly Pulls to Refresh (PTRing) their profile picture of places they are taking a person or persons on a date. This can beach pictures, dinners, concerts, live events, and anything the morning after.
Do you remember when Kyle took Carey on a PTR Date on Clubhouse? He started PTRing pics of where he wanted to do with her like eat crab legs, hit up a concert on the beach, and making her breakfast in bed.
