This was used to refer to both Corey Haim and Corey Feldman. These child actors, turned into bad teenybopper actors. Corey Haim was the good one, and Corey Feldman was the "bad boy". Their acting seemed to go from corny, to gut-wrenching awful. It didn't matter, they sold lotsa teen magazines and didn't do all that bad at the box office, at first. Two of their most successful(?) movies were License to Drive and Dream a Little Dream. After that, they turned out movies that were so bad, they went straight to cable -- nevermind video.
