Replying to Haha girlfriend on NS

So I made my girlfriend an NS account (ilikenutz) for fun because she always sees me on it and wanted to try. She skis, so it's legit. But she's been browsing around and is slowly noticing all the NS jokes and crap, and asks me about them. Tonight she said, "Oh yeah, what's with everyone's obsession with peeing in butts??" I had a good laugh and explained it to her. There are so many weird NS things. It's hilarious seeing a newcomer get acclimated with NS. Anyone else got any stories of "outsiders" finding out about weird NS stuff?
