  • Gas Release: a butt at the gym, pressure meter rising, waiting for a loud moment.

    Hold it in. Let it go while something loud covers you.

    Tap as each bite reaches the teeth.

  • Wipe Rush: a messy butt in a bathroom, ready to be wiped.

    No TP in the woods. Catch the soft leaves.

  • Porta Panic: a festival portable toilet with a paper roll and flies.

    Unroll, tear on the line, mind the flies.
