Sturdy girl 

A female who was a big bottom half, who can't be toppled over, because her heavy bottom half anchors her to the ground.

Shane: Hey Brad, that bitch has a cute face and all, but she's got a case of the bigger-bottom-half syndrome.

Brad: Yeah, try to push her over. It's impossible. She's a sturdy girl.
