the sensation one experiences--ie, on a roller coaster, or a very high swing as a child, or driving fast down a steep hill, or falling in a dream--that causes your body to suddenly tense and your anus to pucker inward reflexively and with force, as if your ass is 'biting down' as a result of the sensation; an autonomic ass pucker
