A perverted person that ogles over young, fresh meat, i.e. Young girls if he is straight or young to pubescent boys if he is gay. A jamonero is very open about being such and approaches his or her victims in a lecherous manner imposing sexual favors to be paid by cash, material items, etc.

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.
