To dream of a pimp represents a comfortable attitude towards exploiting advantages or resources. Feeling good or benefiting from using someone or something to win no matter what. Knowing how valuable something is and taking full advantage of it. Not caring about what anyone else thinks if it means winning.
Negatively, a pimp may reflect going too far exploiting an advantage or resource. A total lack of concern for standards or respect to keep yourself exploiting a situation. Pandering or the embracing the lowest standards to get ahead. It may also reflect forced exploitation.
