"you want to battle me? you need to get your weight up -- you cant beat me."

"Get your weight up means I don't care if you're at school, I don't care if you're working at McDonald's, it's all about elevation in life. It's all about taking your life to the next step, and that's what I mean by that. I see a lot of people who run around here, man, and they just talk all the time about dope, and it ain't just about the streets and you getting your weight up. I know a lot of school cats who are trying to achieve their goals themselves, so whatever goals you achieve is getting your weight up." -Stank
Quit fuckin' around and get your weight up homie.
