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"

Get a NSL mug for your boyfriend Vivek.
An acronym for non-sexual love. This refers to a love which exists, but is in no way sexual.

This love can be love shared between family members, heterosexuals of the same sex, or even heterosexuals of different sexes. The only condition is that sexual intercourse is not an aspect of that love.

NSL is not limited to humans. NSL can be shared between a human and animal, and even a human and object.
