Phrase used to promise great vengeance for a supposed wronging. Vaguely religious undertones, but not necessarily religious in nature (i.e secular-inspired violence is acceptable)

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.
