After smoking marijuana, or some dank, dedankifying is the process of ridding yourself of the smell, red eyes (usually with eye drops), and other signals that you were smoking marijuana. Dedankification is usually done by driving really fast with the windows down, chewing gum, and using eye drops such as rhotos or visine.
