1. (A term used to describe a caucasion, usually male person, who talks, dresses, and acts as if they are black. Many of them prefer having black friends over having white friends, some even have no white friends at all. They wear high top sneakers, triple fat goose winter jackets, baseball caps with a flat rim brought down almost as far as their eyes, and jeans that are 5 sizes too big which hang very lightly over their hip bones. Many speak as though they were Dr. Dre himself.)
2. (A white person who WISHES, whether secretly or not, that they were black instead of white.)
*note added: This term applies ONLY to caucasian people, as speaking "black" basically means to talk like you're a rapper, and there are MANY hispanics and asians out there who talk this way but yet you may not refer to them as "wiggers."
John: "Daaaaag yo, that bitch is bangin', dog!"
Eddie: "Dude, stop speaking ebonics. YOU'RE WHITE! You're not in N.W.A."
John: "Maaaan, why you gotta hate on me all the time, G?"
Eddie: "Cuz, I'm hoping that you being a wigger and all is just a phase you're going through, and that it'll be over soon!"
