Over the pants blow job. When a slutty girl is too prude/ hasn't consumed enough drugs and alcohol to give an actual blow job. This originated in Lake park, FL. When a friend of mine was mad because the girl he was trying to hook up with only put her mouth around his penis over his pants and twirled his tounge.
