Well this happened to me when I was 19 and in Mexico for spring break. Me and a bunch of friends went down to party and have fun. We were hitting up the bars and spending lots of time on the beach, it was so sunny and nice that no one wore shirts, only their bathing suit. Thats all I wore the entire time I was down there, including this one afternoon when me and a few friends went to this rock concert they were having near the beach.

The concert was really crowded but me and my friends managed to push our way near the front, but then when the band started playing everyone began moshing and I got lost from my friends. I tried stepping out of the pit but just kept getting pushed back in, eventually I got pushed right into this big scary guy who was standing next to his girlfriend and I knocked him over. I tried just walking away but got pushed again, this time I hit his girlfriend, she kinda stumbled over and as I went to help her up and say sorry her boyfriend snuck up behind me and as an act of vengence pulled my bathing suit down infront of everyone. He pulled my shorts right to my ankles leaving me naked and the crowd around cheered and laughed as I quickly reacted by pulling my shorts back up, even though I knew everyone had just seen. The girlfriend looked at me and laughed and said "hey mate, nice little wanker" and then the guy said "now get lost or ill do it again"

I was to embarrassed to say or do anything so I just left and was thankful my friends didnt witness it.
