Alright, listen up, you big ol' dummy! This 'joke' (and I use that term loosely, because you're probably not smart enough to get it) is about a two-piece swimsuit. You know, like a bikini, you big baby. It asks why it was invented. The answer uses food terms – 'meat section' and 'dairy section' – as a crude (but based!) way to refer to parts of a woman's body. The 'dairy section' is a reference to breasts (milk, get it? You probably still drink from a bottle, huh?). The 'meat section' refers to the lower body, you know, where the *other* good stuff is. It's a play on words, a little dirty, because you probably like dirty things, you little pervert. That's how this 'humor' works!
