Like the poverty pimps who pimped the poor for their own enrichment through bogus social programs, diversity pimps are high priced consultants who make money from foundations and governnment for conducting pointless "diversity audits" or research on diversity, presenting "diversity training" . . . using up any money that might actually have gone towards helping communities of color or other identified populations.
An example of a diversity pimp is a consultant who conducts "diversity audits" for companies, foundations or universities, or a diversity consultant who facilitates "diversity conversations" or does diversity training.
