When one discovers later after taking a shit that tolit paper has been stuck/crusted in his asshole leaving little white flakes on his ass hair and ass hole, causing the term "cottontail".
Man, i was in the shower and found all these white things in my ass, i was cottontailin all day long and didnt even realize why my ass was itching so bad.
