The letter on the chest is "DRINKING TEAM", inspired by the "Hollister Riot" in 1947. It was originally a carnival Gypsy tour motorcycle rally, but under the influence of alcohol, the riders caused drag racing and fight. The person who caused the incident was identified as a member of the "BoozeFrighters" club. The AMA (American Motorcycle Association) subsequently declared that 99% of the members were good, and only 1% were bad. But, people with a rebellious spirit all claim to be part of the 1%.
