when two people are "talking" and they dont want others to know because it may ruin a relationship or friendship between them and other people. also when there is a secret or suprise for or about another person.

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.
