Definitive proof that it's all about diet. This'll be self-indulgent and absolutely douchey. Downvoat at will. Just spent my first 24 hours with a new lady-friend (uhhh... "in bed"). I'm 42. She's 38. I work out daily like a motherfucker to not be fat (also, old-man gainz). She does absolutely zero conventional exercise. She's working her butt off* to finish her PhD and such stuff, but no running and no gym. Thing is, she's a gorgeous, petite Brazilian of African descent with seemingly negative body fat. With a firm, tiny, utterly glorious bubble butt. Also, she eats to her appetite's content (I made 120-day bourbon-aged steaks last night. She bad-mouthed Canadian beef on our first date and she won't any longer) and loves veggies and otherwise good food and drink. She just doesn't overdo anything and is proud as fuck of her body, as she should. As a French-Canadian, I've had many decades of petite-butt appreciation. In my advanced years, I think I've found the single greatest female body I've ever known, all ages included. So, yeah, it's what you eat. I'll concede that squatless bubble-butts are genetic though. Also, stay fit everybody. It bloody pays off. *Figure of speech, thankfully.
