someone who isn't attracted to either men or women
or has no sexual orintetion

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.

the opposite of bisexual, you have no sexual attraction to male or female whatsoever.
