A slang term depicting a play in basketball. In said play, a player dunks the ball over top or in front of another player, making a play so picturesque that it may appear on a poster, hence the term, posterized.

Some players may have their own versions of this, such as Greg Ostertag of the Sacramento Kings. When someone is 'posterized' by Ostertag, they are 'Osterized'. This pay is known as 'dirty' and 'ugly' and is generally unwanted throughout the NBA.

Really hott chicks that just sit at parties, and do nothing but look hot, talk shit, text, dance for five seconds, and do absolutely nothing with guys. Compared to a poster, because just like a poster, you can only look at their inutile beauty.
Damn, look at dat poster over there doin' nuttin but postin'.

Look at dat poster sitting on another poster like a post-it note.

Man, you see that fine ass bitch over there sitting with her friends doing nothing but texting, ignoring guys, and gossiping. Yeah, don't talk to her she's a poster.
