To have anal sex with a person who, prior to the
deed, has swallowed a piece of raw bacon with a length of string attatched to it. One end of the string hangs out of the mouth of the anal recipient and as "the moment" approaches for the anal
giver, he yanks the piece of string, causing the other person to
vomit up the piece of bacon. During vomiting, the muscles in the anus become tightly clenched, causing an amazing sensation for the anal giver.
