Meaning
An emphatic 'of course!' or 'absolutely!' — an exclamation of strong agreement, meaning 'how could you even ask / it goes without saying'. 'Yuh coming to di party?' — 'How yuh mean!' (of course I am). Said with a rising, confident tone, it affirms enthusiastically. With a different, sharper tone it can also express indignation ('what do you mean?').
