Whats with the Pinay predeliction for armpit-sniffing

I have lost count of the number of times I have had my armpits "sniffed" in Pinas

I never once had any other nationality except Filipinas ask could they check the fragrance of my "Pits"

Is it a cultural thing like a maoris "Hongi"(rubbing noses)

Or have I just met the wrong sort of ladies
