A type of motorcycle helmet that enables motorcycle riders to be in compliance with the law where helmets are required, but offers inadequate protection, about that of a bicycle helmet
When he wrecked his motorcycle, he still got his face scraped up and his jaw broken because he was only wearing a brain bucket instead of a full face helmet

Northern California slang word for a helmet, often of the old military "steel pot" variety. It's worn by the neo-Nazis in the area.
Neo-Nazis and other wing nut types sometimes congregate and hold rallies in NoCal, or the Pacific Northwestern states to promote their hateful agenda. Some of them wear Klan Klown Konehead sheets, some wear brain buckets, some wear camies, some wear swastikas or other fascist insignia. It's funny that the helmets are called "brain buckets" because there's no brains in the thick heads underneath them, just piles of shit!
