A specific act performed by those who engage in "watersports," wherein one partner (of either gender) urinates into the ear of the other willing partner (also of either gender). The ear mimics the shape of the "rose."
"Man, that girl is a next-level freak. She told me she wanted me to give her a Boston Pancake and then water the roses when I was done."
