Friends who are very intimate or affectionate, but not in a sexual nature.

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.

A friend of the oposite sex that you don't want to sleep with. Or, if you're gay/lesbian, a friend of the same sex that you don't want to sleep with. Or, if you're bi and your friend is of either sex and you still don't want to sleep with them.
