"The term "chump provider" typically refers to a situation where one person feels they are being taken advantage of or not fully appreciated for the support, resources, or efforts they are providing in a relationship or arrangement. This term can be used in various contexts, including romantic relationships, friendships, or even professional environments. When someone is labeled as a "chump provider," it suggests that they are perceived as giving too much without receiving enough in return, either in terms of gratitude, respect, or reciprocal support.
