Short for dakimakura, also known as a body pillow is a rectangular pillow that has a printed character usually from anime on one side, and on the other side is a more lewd version of the character. These are mostly used by otakus in a form of self pleasure.
If you have one of these, you should probably go outside.
Scott: I just bought a daki with Miku on it, guys.
Trevor: You absolute otaku. Go outside for once!
