A syle of chassis for a Personal Computer. So called because they are usually similar dimensions to a cardboard Pizza box from a take-away restaurant. Pizza Boxes are slimline in comparison to regular full-size PCs.

Sometimes when you receive home delivery of Pizza the box can get a bit crushed. When you open the box the mozzarella cheese sticks to the top of the box and strings of cheese go from the pizza to the box. This also can happen when you pull down a pair of women’s panties. There will be a cheese like substance stringing from her diseased virgina to her panties. The smell can be worse that the visual. It may be a wicked case of vaginosis. This syndrome is most prevalent in females with large gunts. It also is found when women get large amounts of jizz dumped into their said cunts on a regular basis and do not bother to wash out their snatch.
I was pulling down Joan's big panties last night and I saw a string of cheese from her cunt lips to her droors. Yuck, she must have Pizza Box Syndrome!

Hey Edwin, I tried to fuck your nasty mother last night when I saw her laying in a pool of her own sick outside the bar. When I pulled down her pants I saw "Pizza Box Syndrome", so I left her there for the Mexicans.
