Transform yourself into the latest Internet sensation at the fifth iteration of this annual social-media–savvy soiree. DJ Chambaland will spin meme-themed tracks while a video installation documents five years of online pop culture. YouTube stars and high-profile bloggers will be among the judges mingling with the crowd—which will doubtless include more than a few Grumpy Cats and Ylvis foxes—to spot the best costumes, but whether you win or not, get snapped in the free photo booth for real-time Instagram glory. R.S.V.P. is required; visit hallowmeme2013.eventbrite.com.
RECOMMENDED: All Halloween, NYC coverage
