"I just got my hood pierced, wanna see?"
Some random (rather attractive) girl walked up to me with some friends while I was working outside and said "I just got my hood pierced, wanna see?" After my obvious response she then proceeded to remove her pants and show me her new clit ring. After close inspection I believe I said something like "Wow, that's the greatest thing I've ever seen!" She thanked me, pulled her pants back on, and went on her merry way. In hindsight, there was probably more I should have done/said, but I guess I was just too shocked and confused about the whole thing to really react appropriately.
