look up any word, like hipster:
 
1.
An act of precautionary racism, crossing the street is undertaken by white men or women when a larger number of young black men are walking towards them on the same side of an otherwise quiet or dark street. While it is becoming more widely recognised that most black men are non-aggressive, it's better to be safe than sorry.
I saw a black man coming towards me while I was wearing my Nikes and listening to my IPod, so thought I'd cross the street early just in case.

2.
A caution to give someone before they make a racist, sexist or age-inappropriate joke or comment. To look both both ways before saying something that may be offensive or get you beaten up or in trouble for being a racist.
Guy1: "So a Jew, a Black guy and a Hispanic walk into a bar..."
Guy2: "What the hell are you doing? Did you cross the street first?"
Guy1: "Oh sorry. I think we're good"
Guy2: "Thank you. Now proceed with your racism."
