Do NOT Hump - Buffalo Lake, MN from flickr user RyanShoots
In railroad terms, "do not hump" is actually not a sexual phrase, instead to "hump" refers to the practice of assembling trains (uncoupling/recoupling train cars) by pushing the cars up a small hill or hump and switching the tracks to the appropriate set of rails and assembling the trains that way. The warning of "do not hump" on the side of rail cars can be due to sensitive or dangerous materials they are carrying.
