A FartBox McJohnson, or FBM, is a contraption comprised of a cylindrical cardboard tube (normally used for toilet paper rolls) placed upon the Farter's anus and a recipient, the Sniffer, placing their nose on the other end of the tube. By sniffing the FartBox McJohnson, Sniffers receive life in heaven.
