"Xaropinho is how Uflacker is best known in Brazil, a name which relates to a character from a famous Brazilian Tv show called 'Programa do Ratinho', who was an anthropomorphized mouse with large front teeth and big ears. When Christian started jiu jitsu as a child, he also had very distinct front teeth and for that reason his instructor Márcio Feitosa started jokingly calling Uflacker that nickname."
