doting on someone like a pet; spoiling someone rotten
Noun form of the verb 可愛がる (kawaigaru), which is derived from 可愛い (kawaii, 'cute, lovable') with the suffix がる (garu, 'to show signs of, to behave as if'). The ironic sense developed from the idea of 'tough love' in hierarchical groups like sports teams.
