Cottontail
Cottontailing occurs when a piece of toilet paper rips during mid wipe, leaving a small piece of T.P stuck to lingering poop. As a result, the victim is left with a "cottontail" protruding out from the middle of the butt crack; resembling a small white tail, much like a cottontail bunny rabbit. This can also be referred to as a Rabbits Foot. Although contrary to rabbits feet, cottontailing is not lucky.
