A unique practice where unimformed, misinformed, or ill-informed, foreigners that know nothing of the history of Pamplona and/or the practice of the running of the bulls, dimisses it to be simply a pastime where drunken farm boys, drunk off of whiskey and barly beer, make their way running through town as they are being chased down by a pack of angry, yet amused bulls.

These boys often scream in terror, shouting phrases like "Owch! my stomach lining!" or "My blood hurts!" Or something of the sort while, routinely, but traditionally, being gorged, or even gutted by the horns of a bull.
The running of the bulls festivals is held in Pamplona, Spain, every year, for nine days in July.

An extreme sexual manuver when a man is on top of a woman and the man tries to throw the woman around the room while still maintaining insertion.
