When "putang ina mo" is righteous anger.
"The charge of oral defamation stemmed from the utterance of the words, "Agustin, putang ina mo". This is a common enough expression in the dialect that is often employed, not really to slander but rather to express anger or displeasure. It is seldom, if ever, taken in its literal sense by the hearer, that is, as a reflection on the virtues of a mother. xxx."
