Residents of trendy neighbourhoods of Friedrishain and Kreuzberg, once separated and now administratively unified, take part in this messy food and water fight every year, according to AFP. And according to some reports, even dirty diapers have been used in the fight, making the fight even more murky.

In this AFP video, thousands of particpants last Sunday could be seen donning protective outfits and wearing helmets and using shields to protect themselves from incoming tomatoes and eggs. Though one good part of the festival is that only rotten food and cooked vegetables can be used. It is believed that the fight is used to give people a platform to vent their anger against the merger.

Both sides position and meet in the middle of the bridge and start their attempts to push, beat, scare and intimidate their opponents to the other side of the bridge, giving them a feeling that they are the masters of the district.

The most funny part of the battle is that both sides have their own smaller teams of combatants who have their designated responsibilities. As an example, there are the Kreuzberger Landwehr ("Kreuzberg Militia") and the Kreuzberger Patriotische Demokraten/Realistisches Zentrum ("Kreuzberg Patriotic Democrats/Realistic Center") on the Kreuzberg side.

There are the Total Krasse Kreuzberg-Gegner ("Totally Wicked Kreuzberg Opponents") and the Anarcho-Zynistische-Offensive-Berlin-Fraktion Friedrichshain ("Anarcho- Offensive Berlin Faction Friedrichshain") on the Friedrichshain side.

Though the event has been mirred in controversies and even banned couple of times, but Sunday's event was played in the best spirits of the game, hinting that the event is here to stay.
