A sexual punishment named after shipping political prisoners to Siberia by rail. This act involves inserting something cold or frozen anally (we prefer Popsicles). The recipient then gets gagged and locked into a box, case, or trunk. The container is then pushed or propelled down one or more flights of stairs.
I gave that bitch a Siberian Express for dessert because dinner wasn't ready on time.
