When you stick a straw in you butthole and connect it someone else's butthole and then fart in it so it goes from your butt to the other person's butt. It is a rare form or intimacy that only the most passionate of lovers (or even friends) dare to try.
She wouldn't believe that I loved her until we tried the fart tunnel. Now we're happily married with two kids.
