"For some reason, it has become some sort of trend for people to hang toys or other items of thier cars' rear tow hook, but the origination of this trend came from the Bosozoku (street gangsters with fixed up cars) in Japan. It was a Bosozoku trend to hang a small tin bucket from thier rear tow hook to show off how low thier cars were- they got the idea from seeing cement trucks in Japan, wich always had a bucket hanging off the rear of the truck. The cement trucks used the bucket as a "catch can" of sorts, so that excess cement from the truck would'nt spill onto the pavement. Inspired by this, the bosozoku trend setters attached small buckets to thier rear tow hooks to show how low thier bucket could hang- if your car was so low that the bucket could scrape on things as you were driving , they thought it was cool as hell."
