yes the word itself "ningas kugon" is exclusively pinoys.

but the nature of the act as what alexa mentioned, is not totally ours alone. it applies to all human being in every corner of the planet.

in the first place, this act may have been handed over to us by all those who colonized our mother country. or it may have been developed somewhere along the way during those long years of boredom, laziness and "uninitiation of the mind" amongst local masses (non elite).

"malay natin, baka mapauso natin ang salitang yan at gamitin din ng ibang hindi pinoy" ;)
