When someone is doing really well in something (usually when they are doing better than what is expected of them), they are on smoke.

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.

Someone who shoots people smoke = gun smoke

Not involved in crime activites.

Simply saying one is acting like they have been using something that puts off smoke that will intoxicate them.
