Recently found out that my ribs are ticklish. I was with someone I know (a female) and made a sarcastic comment or joked about her. In return, she went behind me and started tickling my ribs. Before this day I wasn’t sure if my ribs were ticklish, but I was squirming back and forth, trying to get away from the tickles as I laughed and laughed. This probably last 20-30 seconds then she stopped!
