That man is into scamming, and with a stomach like that, you honestly believed and thought he wasn’t going to scam you? Can't you see that his huge stomach has swallowed so many—or a lot of—things for him to be able to afford a comfortable lifestyle (or soft life)?

That lady over there doesn't love the man she is with. She is only going to spend his money and leave him for another trick because that's how she roles.
