Like this myth of Midas, only in a bad way. Someone with the touch of shit makes everything they touch turn to shit. Often applies to celebrities and musicians, thought can also apply to politicians, teachers and occassionally significant others.

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.
