There is no such thing as fat strength, there are strong people who are fat (which you'll know cause it's usually some perma dirty bulking weightlifter), but it's mostly because it's impossible to see how much muscle mass is under some peoples mayo bags. I assure you the vast majority of fat fucks don't have "fat strength" that is just what fatasses tell themselves so they don't have to admit despite being 3x the size of someone else they're still functionally weaker in every way.
