[849] Origin at Sāvatthī. Now at that time the bhikkhus of the group of six ate sticking out the tongue … "I will not eat sticking out the tongue" — thus the training is to be undertaken.
One should not eat sticking out the tongue. Whatever bhikkhu, out of disrespect, eats sticking out the tongue: an offense of wrongdoing (dukkaṭa).
There is no offense: if it is unintentional; if he is unmindful; if he does not know; if he is ill; in emergencies; if he is mad; if he is the first offender (ādikammika).
