Women who sleep with law enforcement officers, but would never have done so had they not been a cop. Holster whores will often work their way through entire police departments, sometimes even as large as a Sheriff's department.
Holster whores are sometimes themselves law enforcement officers, or dispatchers / clerical workers at police departments. Their close proximity to cops will eventually wear down their inhibitions until all they see is a badge, gun, and the ability to beat people up and not get in trouble.
