What fad? Bad Boy has been with MMA from the beginning, sponsoring the likes of Vitor Belfort, Mark Coleman, Ricardo Arona, Mark Kerr, Minotauro, Macaco, Rickson Gracie, Wallid Ismail, Dean Lister, Bob Sapp, Jerome LeBanner, Godoi, etc....
LeBanner is still on the team, and they just signed Lyoto "The Dragon" Machida and Mauricio "Shogun" Rua. Check out
BAD BOY.
Hansen probably bought those shorts in Brazil - the ORIGINAL Bad Boy Vale Tudo Shorts are still sold in Brazil, where the manufacturer is. Casca Grossa was purchasing the shorts through a third party who no longer has the license to sell Bad Boy in the USA. Now, Bad Boy is planning to re-release the original design and a new, longer version in the USA through their new website.
The USA tried to kill Bad Boy, but couldn't. Bad Boy lived on, just like MMA; in other countries, in back alleys and on the streets. Every fighter is a Bad Boy at heart. That's why Bad Boy is more than a fad with MMA.
