Answer
Dopey, the lovable and absent-minded dwarf from Disney's "Snow White and the Seven Dwarfs," is the inspiration behind Dunga's nickname. The Brazilian footballer's slow and deliberate style of play, coupled with his tendency to make occasional blunders, drew comparisons to Dopey's clumsy and endearing nature. This playful association has stuck with Dunga throughout his career, becoming a humorous nod to his on-field characteristics.
