Similar to a normal game of flip cup except teams of two compete. One player on each team gives their teammate a piggyback and then each team races to drink and flip. The teammate getting a piggyback must drink and flip their cup from their teammates back. Each round the slowest team is eliminated until the fastest team is left standing.
