A Caucasian woman who chooses to see a black man romantically. The term derives from the phrase nigger lover by sharing the same initials and has the same meaning. The term is most commonly used when the phrase nigger love is not appropriate, as well as when discretion is needed.
What's that girl doing over there with that black guy, she is being a total national leaguer.

Kim Kardashian and Heidi Klum are huge national leaguers.
