Appearing on Conan on Wednesday, Thomas Middleditch explained that the Silicon Valley cast members are pretty obsessed with this game called Credit or Debit. It’s really less a game and more, as Conan puts it, the act of using one’s hand to swipe the fissure that separates one buttock from the other. That’s not all: Middleditch also had some new entries for Urban Dictionary, including another definition for Bitcoin.
