I got pantsed bare bottom [I Got Pantsed]

Me and my best friend have been In a prank war for a long time lol. But one time she caught me way off guard and I’m still waiting to get back at her. She was over with me playing ‘Just Dance’ my my 14 year old brother Was playing too, my dad and my Grandpa were behind up having a conversation. I was 19 so I was the older sibling and my friend was 19 as well, but as we were dancing my friend went behind me and pantsed me bare bottom 😂. I was embarrassed at the time because my friend said when I bent over to pull my pants up, I accidentally exposed my butthole to everyone lol but now I find it funny honestly, I’m just thinking of a funnier prank I could pull on her.
