"plain view" exception
A loophole in da generally-accepted social rule which states dat you hafta keep yer paws off a buxom gal's "merchandise" less'n ya get her permission beforehand --- da theory in dis case is dat if she has a majority of her plump juicy "milk-thingies" juss hangin' right out there all luscious and "obvious", she is implying dat she is largely "tossing social norms out da window", and so you can go ahead and gleefully "squeeze theeze" without having to ask her first.
I'm guessing dat da brainless lunkhead in da classic "PAT"-labeled-uniform cartoon (da bosomy chick who's wearing da name-imprinted t-shirt is named "Patricia", but da clueless dude thought dat da word meant dat he had permission to feel her up) who got KO'd by da brawny babe was thinking of da "plain view" exception when he decided to delightedly "savor da goods" with his huge clumsy hands... da guy's buddy is saying to him, "I think it's meant for identification purposes, not as a set of instructions" :P
