(Dear everyone under the age of 45-50; a "zap" is a small, squashed thin piece of hash, positioned between the flat side ends of two butter knives, which allows you to hold the knives over the stove until they heat up enough to make the hash smolder, at which point you position the very hot knives under your lips (but not too close to your face) and inhale. Be warned, it is VERY EASY to fuck this up and permanently scar your face, so don't do too many zaps at once.)
