Geddan or whatever is a meme that spawned from cartridge tilting of the game GoldenEye 007 causing the player models to thrash around spastically. On July 12th, 2007, somebody uploaded a video to Nico Nico Douga that demonstrated that when the cartridge for GoldenEye was partly removed from the console, player models would thrash around in the air. 12 days later, someone put together the Japanese song "Promise" by Kohmi Hirose with the video mentioned earlier.
