I lived in co-op housing during college, which was (loosely) administered by the university and separated into different buildings by gender. One year my hall started a rapidly-escalating prank war with a women's hall when some guys testing a water balloon launcher accidentally put a balloon through their back window from like 100 yards away. Things culminated in a massive water balloon fight on the campus quad that both sides referred to as the "Bitches and Bastards Brawl."

The past truly is another country.
