She pinched/grabbed my bum

I was talking with Gabby and Rosie. They were going to the kitchen to make cheese sandwiches. Using the little sourdough rolls. So Rosie says "we have the cheese and just need the buns." She grabs one of my butt cheeks and pinches it. Then she gives it a quick slap. Dang Scarlett, you have a nice ass. I slowly backed away from her. LOL
