FartBox McJohnson

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.

Fartbox

Another word for Anus (end of your rectum where you release gas/fart and excrete.)

I'll shove my hard cock up her fartbox.
