How is the flip conducted?
A coin is tossed by one team and called by the other team. The team which wins the flip may choose EITHER the side of the topic they wish to defend (pro or con) OR the speaking position they wish to have (begin the debate or end the debate). Once the coin toss winners select their favorite option (i.e. they choose to have the last speech) then the other team makes a choice within the other option (i.e. pro or con). The analogy here is to football: Toss the coin and the winner chooses to kick or receive OR the side of the field they wish to defend.
