See pass around. Women that have been passed from one man to another man(usually a buddy or friend) in serial usually as a sex toy, but sometimes as a mistress.
The man doing the passing assures the next man in the chain that the woman has desirable characteristics like she puts out, is disease free, and is discrete and do not kiss and tell, and can be trusted for anything from a fling to a longer term sexual relationship up to and include being a mistress.
She has been passed around the football team since she was in Grade 9, and from there, she was passed around the basketball team and then the soccer team. The best part about her is she will 'pull a train' for the entire team.
