The Transfer is completed when two people line up their anuses hole to hole, and one shits into the other. EXTREMELY difficult to achieve, which is the main reason it's legend is so massive.
The Transferrer has to push outrageously hard, and generally you want The Transferee to have an extremely loose, empty, and wet hole.
Dude, these two chicks are soooo fucking drunk in that room. You think we could convince em to do The Transfer?!
