Top Definition
The undercover love interest of a man who is engaging another woman outside his marriage or relationship. To his wife or girlfriend, this extra girl is a friend, when the truth is he and this "play sister" may have been intimate in the past, but the relationship did not work out.
She's just my play sister - there is nothing up between her and I.
