When a Police Officer or other authority figure representing a government or private entity searches you by using his or her hands. This is usually done to hot, boobular females by both male authority figures and females who would rather the touch of a woman's body to that of a man's. In most cases after cop a feel is completed the female and or male being "copped" is let go unless a serious felony has occurred. "Cop a feel's" usually only occur when an authority figure is bored and or horny.
Barbara felt kinda turned on when the female police officer pushed her over the trunk of her car, spread her legs and did an in depth cop a feel.
