> Like the buttock of Titechingai.
He rushes crazily from one task to another. Titechingai had a disease which left his buttock covered with old sores and pock marks. Therefore, when Titechingai called on a young woman at night, he always left the house before it became light in order to avoid being seen. Once, however, when he awoke it was already light and he was observed to dash from bush to bush in his desperate attempt to run through the village with minimum exposure. A person who seems to be rushing madly about in the conduct of several tasks may be compared with Titechingai.
