Hammer is a meme from the episode Stare Master relating to the asking and passing of hammers by the Cutie Mark Crusaders. Shortly after this episode's airing, it would be common for posters to request, and pass, a hammer, often with various pictures of hammers. Sometimes this would combine with the 'STOP: Hammertime!' meme from around the internet, and it would also combine for a short lived derail 'And My Axe!' by giving someone thier hammer (from lord of the rings), rather than axe.
