bigger booty

ok so I have always been insecure about how skinny I am, I'm more or less straight up and down, and I do squat after squat and my butt just will not have it!! my mom definitely didn't mean to offend me when she said this, but she was talking to a friend about their daughter and how gifted she was back their and they commented "yea, she has a very girly shape" and my mom says "no, THATS a girly figure" and points at me "your daughter has a womanly figure " even though I know she didn't mean to make me feel bad, it did. I'm 18, I don't want to look like a little girl. what can I eat that will go to my butt? if I ever do gain weight, it's in my stomach.
