Cow tipping is the supposed act of sneaking up on a sleeping cow and knocking it over for fun. While it sounds like a wild rural adventure, cow tipping is mostly considered an urban legend, with many dismissing it as exaggerated stories. The idea that country folks engage in such antics out of boredom is just a stereotype. The whole concept seems to have popped up in the 1970s, though myths about animals being unable to get back up date back to Roman times.
