HOW CAN SHE SLAP?!? is a meme that originated on September 6th, 2008 when some newfag posted a link to an Indian game show. Apparently, the show's planners failed to brief the contestants about not losing their shit on stage, because when the hostess delivered an unscripted slap to a contestant, he returned fire with a GB2KITCHEN that was so hard, it practically knocked her backwards inside her clothes. The crew thereafter decided to fulfill the prophecy.
Forget "Doomsday vs Superman" or "Uwe Boll vs Lowtax"... What followed was a brown on brown reworking of the Rodney King beating.
(Also, I just increased the max amount of vid embeds per page to 100, so this thread should be easier to browse now)
