First of all it's called Fasching it's starting on the 11.11 on 11.11 o'
clock.In some cities they dress up(only in a few, Colonia, düsseldorf and some other cities) and get really drunk.
Most people in germany annoys fasching and pisses us off.
Fasching only exists to give us a intersection from the oktoberfest to mulled wine time so we have a reason to party and drink.
Nothing more to say about it.
