I have something similar to Matt's story.
When I was about 14, my family was RVing, and we stayed at an RV place in downtown SF. This place had a community rec room, pool, showers, etc. I went to go use the showers, and there were a group of guys hanging out in there. I was old enough to know that SF had a gay reputation, but really had no clue about any sort of gay culture. So when I walked in and one guy says "hey kid, come here. you have to check this out. over here, in this shower stall." , well, I was a bit freaked out. I asked what it was, and they just said that I had to check it out for myself. I was very freaked out, but being the age I was, I didnt want to appear to be a chicken shit and just run out of the place. So reluctantly I went over there, keeping an eye out behind me. I pulled back the shower curtain, and there it was. A turd. A giant one. laying there in the middle of the shower stall. This thing was the size of a half grown puppy. All I could do was shout "what in the hell is that?!". All the guys laughed. I was so relieved after that. These guys were just so amazed by it, they were hanging out in there just to show it to anybody who wandered by. I was still in a bit of shock. I hurried over to another stall, showered, and left. And they were still there, looking for people to show this thing to.
