I always call them my Electronic Nicotine Delivery Systems. But I get sorta formal about stuff like that.
why not call them "death sticks" or "cancer death sticks" ? at least it accurately depicts the dangers of using them.
"Coffin nails" was the one I liked. Now I guess it's used for some fingernail design. My daughter always tries to keep me current. I thought she was talking about having a half pack of cigarettes at the nail salon. And she doesn't smoke.
