Tattoos?

"Piercings? C'mon, it's a piece of metal in you. If you had a car accident and part of the door was stuck in you, you'd want surgery, no?"

Anyway, I saw a guy with 水友 on his back, which is either "MizuTomo", "SuiTomo", "ShuiYou" or something else. Jap, Jap, Mandarin. So, either, Water Friend, Wednesday/Water Friend or Water Swim. Or y'now, I was thinking and I thought about "ShuiPeng" as in, "PengYou", but it's not quite right, and that would mean Water Pan. Bed Pan anyone? Then again, intonations and such. Still, Water Pan's pretty darned funny.

Hoping someone knows what it REALLY means.
