An acronym for
Non-Sexual Lovers, which describes a special bond between a man and a woman (usually occurs between a gay man and a straight woman but there can be some exceptions to this rule). With NSLs there are
no sexual feelings at all but a strong
legitimate love, that is more than friendship.
"Are you and he
dating?
"No, he's actually gay but we really
love each other, in other words, we're NSLs"
