An Oops situation (a.k.a. an Oops) is a spontaneous voyeuristic situation, where bystanders have the chance to see and to snapshot private body parts they are not supposed to see, especially tits, ass or pussy and also lingerie items as panties or bra. Most often the oops situation is caused by some kind of malfunction of her clothes.

Nipple oops means that at least one of her nipples becomes visible in public without her intension. If this is caused by wardrobe malfunction, it is called nipple slip otherwise it is the more general nipple oops. As a milder type of nipple oops also pokies might be considered nipple oops situations.
Some women forget to wear knickers with short skirts or go pantyless by intension and then also forget to keep their legs together when seated, getting out of limousines or looking at items on the bottom shelf in shops or supermarkets. Of course this usually allows a great view of her pussy. Another major pussy oops caused by malfunction of her clothes is the lip slip.
Bikinis are always good for unintended spontaneous oops situations listed under bikini oops.
Wearing see-through clothes without being aware of transparency of the fabric is a true oops situation and discussed under see-through in public.
