one on one
A direct encounter between two persons, especially a conflict, as in The two department heads went one on one regarding shelf space. This slangy expression almost certainly comes from sports. It is commonly used to refer to a two-person basketball game, but is also applied to the interaction of two players on opposing teams in football, soccer, and similar team sports. [c. 1960]
