piercing play 

Piercing one's self in any area on the body with safety pins, needles, or other sharp objects for either the intense feeling of the pierce or for sexual reasons.

"hey, what are all those scars on your arm from?"
"oh, this one time i was bored in my english class.. so i went kind of crazy with the piercing play and stuck some safety pins through my skin"

play piercing 

A BDSM practice; puncturing the skin of the body, genitals, nipples, and less often, the face with hygenic (hypodermic) needles for pleasure and temporary decoration. Afterwards the needle is removed and the wound is allowed to heal. (Unlike regular piercing, which is intended for the insertion of jewelry.)

Even though play piercing can be dangerous, Ruth had been very interested in needles since she'd had her lip peirced.
