When it comes to mafia, gang, black ops (not the fucking video game), and other shit the "trigger man" is the one who ties up the loose ends. A dirty job but the trigger man makes sure one whistle blower doesn't mess up a well planned operation, robbery, hit, etc. If you don't have the heart to be the trigger man, there will always be a bastard out there that won't bat an eye over doing it.

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.
