After ‘planking’ seemed to have swept over Hollywood faster than you can say ‘Kabbalah,’ there’s one lonely adversary who’s standing up against those that are laying down. Rapper Xzibit took to Twitter to express his extreme disapproval of the trend.

“Planking is THE dumbest sh-t ever,” Xzibit tweeted (via TMZ). “#Planking was a way to transport slaves on ships during the slave trade, its not funny. Educate.”

From Rosario Dawson and Ellen Page to Justin Bieber and Katy Perry, celebrities have been laying down straight and narrow left and right.
