Why do some beer bellies feel firm if they're caused by extra fat? Why aren't they soft and squishy like fatty tissue in other areas of the body?

Okay, so odd question, I know. But sometimes when a man gets a beer belly, it can feel kind of firm, like the belly of a pregnant woman. I searched a little online for why, but all I could find were "causes of beer bellies" which, is obviously extra calories leading to extra fat.
What I want to know is why the beer bellies are firm instead of feeling soft and squishy like other fat.
So why is that?

This is not specifically down to excess fat as a result of calories in alcohol, but down to the difference between subcutaneous ('soft') fat and visceral fat, which is fat stored deeper in the body, which also feels firmer.

For reasons mostly down to genetics, some people divert excess calories to visceral fat, while others produce mostly subcutaneous fat. This is largely responsible for the difference in 'feel'.
