The term originated from a little known Taiwanese video game based on the movie "Kung Fu Hustle". In order for users to transfer from one instanced zone to another, the user would click a sleeping cat located in the game world. Upon clicking the sleeping cat, users would be prompted with "Sniff the cat?" accompanied by trippy East Indian music.
In a sense, this represented the user taking a psychedelic and transferring from one reality to another. An experience often had by those who smoke salvia.
Guy 2: Sure.
