Is a basketball play where the ball is thrown towards the rim by one player and another player jumps to catch it and dunk it before touching the floor. A basketball slang term given to the sickest alley-oop dunks.
Allen Iverson threw 2 sick Dunkadelic Alley-Oop's, one to Andre Iguodala and the other to Chris Webber last night. During the 2005 All-Star game Vince Carter threw himself a rediculous Dunkadelic Alley-Oop that was the play of the game.
