A phrase typically during road rage--especially when being glared at by snotty female passengers. This phrase can be used in conjunction with hand signals, but is more typically exercised as a way to blow off steam at those road neighbors who just seem to have an issue with the fact that they are sharing the interstate with other individuals instead of owning their own highways.
To be used interchangeably with the phrase: "rub your nipple." The word 'pet' may also be subbed out for something fitting with the circumstance, such as the words 'squeeze' 'smack' or 'flip.'
