for a woman to back that thang up, or to put her booty on a man, while dancing; to be supported by something/someone; to firmly agree with/to something; to submit to something;
As in, "I like the way you're moving on the dance floor especially when I'm behind you and your booty is bouncing like that. Trust me, I'm a strong man, so, get it shawty!...g'on and put your weight on it."
