noun 2) short for woahday/wodie. A wodie is a friend, partner, compadre, or just a pleasurable acquiantance. This term definitely came from Juvenile... it seems to have started off as describing things as "woah", things that give off a "wow/woah" reaction then became a greeting for meeting pleasurable people "woah!" instead of "hey!", then somehow evolved into a name for those pleasurable people.
2) "what's up woooahh?" "what's happenin wooahdie?"
