If a person 'bats and bowls', they are bisexual.
Similar to the phrase 'bats for both teams', this expression derives from the sport of cricket in which there are, broadly speaking, two types of players: those who bat and those who bowl.
Person 1: "Victor asked Samantha out not realizing that she isn't into guys."
Person 2: "Nah, he had a shot because I think Samantha both bats and bowls."
