Why do people say it will rain if someone sings??

Question

Everytime one of my friends sing, someone says "Wei! Nanti hujanlah!" (in English: Hey! It'll rain!). Why do people always say that??

Answer 1

here they say if you hear crickets or frogs singing its going to rain

Answer 2

It could be tied with tradition...

Answer 3

People always say that?? From where I live.. Nobody says that. You must be living in the countryside.

Answer 4

Interesting!  I've never heard that one.  It's a good thing it isn't true though, or it would be raining constantly where I live. :)  What language is the quote in, by the way?  I'm curious...
