Granted. The reason why women constantly burp/hiccup is because they eat large amounts of food every meal; the digestion process in turn causes a significant build-up of gas which frequently comes out of the mouth. If women aren't burping, they are hiccuping because the constant burping messes with their nervous system, specifically the part that regulates breathing.

There are a few variants of this whole "women eat a lot" phenomenon. Some women eat gigantic meals, enough to comically inflate their bellies; and they they swiftly revert back to normal size after an hour or two. Other women instead retain large amounts of fat, ranging from "very chubby" to "still-mobile-somehow fatblob"; ironically, these women's bodies tend to extract more energy from food, meaning that they eat less food overall compared to other categories. Still other women eat people whole, somehow extracting nutrients from their victims without killing them, and them... well, pooping them out. Thankfully all women no longer produce any actual shit, since they metabolize every single atom of any actual food they eat.
A few rare women develop the ability to perform exceptionally potent burps or hiccups. These quirks, if refined, could be developed into actual superpowers such as sonic "screams" or hiccup-powered flight.

What about men? Well, they live an inferior life. They are frequently smooshed by bellies, stunned by sonic burps, eaten, or some other issue. A lot of men work in the food industry, producing enough food to feed the females. Men overall are treated as a lesser class, good for serving women or being toyed with by them.
