funk duelo is, overall, an event or a phenomenon where two mcs will duel each other in a song or performance as a response to factors such as fan demand or competition - similar to rap battles, talented funkeiros go head-to-head with improvised lyrics in order to win the approval of the audience present and win the contest.

other reasons for duels may involve personal issues one may have with the other - generally an mc will tease or speak poorly of another and a duel will arise.

a popular funk duel is one between mc g3 and mc max - most competitions are usually seen at establishments, as a previously scheduled event, but they can times also be seen in an impromptu manner with friends or funk enthusiasts.
