In Kerala, and perhaps other parts of India, “auntie” or “uncle” are terms of endearment among youth for anyone of “respectable” age. No blood ties are necessary. In many Western cultures the OED definition tends to prevail, respectively, for these two terms:
A sister of one’s father or mother; also, an uncle’s wife (= aunt-in-law).
A brother of one’s father or mother; also, an aunt’s husband (= uncle-in-law).
And cousins?
