ELI5 why do beer guts on guys (I’ve never seen them on women or haven’t been able to tell) look like a pregnant belly (raised with a definite shape) whereas you can tell the larger stomachs caused from bad diets flatten out and have rolls?

"Beer bellies" are specifically visceral fat, meaning it's fat that's on your organs. This is caused by the consumption of **excessive** amounts of calories, not just "eating a little too much". This is also why "beer bellies" are usually very hard to the touch. 

Most fat accrued by just "eating a little to much" is subcutaneous fat, meaning it's just under the skin. This is the soft, rolly stuff you can pinch and squeeze.
