NSL
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"
