When an actor wins an Oscar and immediately begins making a string of films in which it is patently obvious they are whoring for more Oscars. This is especially the case when the character played is sentimental, mawkish, and the film incredibly cheesy. Named after Robin Williams, who won an Oscar for Good Will Hunting, and proceeded to make a slew of incredibly bad films - What Dreams May Come, Patch Adams, Jakob the Liar, and Bicennetennial Man.
"Man, Kevin Spacey's caught a bad case of Robinwilliamsitis - wins his second Oscar for American Beauty, and follows it up with crap like Pay It Forward, K-PAX, The Shipping News, and The Life of David Gale."
