|1.||Post it up|
Also known as: Postin' it up, rock-it-hard, blockin' hard, etc.
The act of one or more people assuming random gangster poses, usually poses that originated from Run-DMC in the 80's. Crossed arms, gangster hats, bandannas, and Gumball 3000/Puma's and 13-14 year old girls are a must to correctly "Post it up."
Kenneth, Seth, and Jeff post it up hard.
Jeff tries to get girls to post it up with them. And it never works.
