This stands for Transcutaneous Electrical Nerve Stimulation. It is used by sending an electrical current through particular parts of the body to block pain in chronic pain situations. Some people use this as a fetish object, where they use the TENS machine to shock various parts of themselves for pleasure (see electrophilia)
Ex1:
Football player: My back hurts.
Doctor: I'm going to put you on this TENS machine for a while, so that it will block the pain.

Ex2:
Sally: I like shocking myself.
Guy: WTF? Well, how do you do it?
Sally: I hook myself up to this TENS machine. It feels stronger than a violet wand, and I like it!
