An archaic word that is only ever used in conjunction with "and behold". In conjunction with the aforementioned words it means "look" or "what happened was".
Short for Polo. Back in the day, Lo-Lifes, Ralphies' Kids, and Polo USA (United Shoplifters Association) would run into stores in NYC and rack madd Lo gear. This is a purely New York City phenomenon.
Also: Kanye West may seem like a Lo head, but he's not. He's a new jack to the game.
