Leadfoot Clothesline occurs when the driver of a vehicle has to
break suddenly at a
high to moderate speed. Concerned for the safety of the passenger riding shotgun the driver thinks that in the event the seatbelt fails, or you are not wearing one. They believe they will be able to prevent you from hitting your face off the dashboard or being ejected from the
car entirely nulling the laws of
motion and momentum, using only but one fully extended right arm. This will always result in a back hand to the chest, neck or face and an immediate apology.
