The Pssst

I was browsing our company newspaper, Gulf News, in the pantry a few days ago when I stumbled in the editorial page:

It was Barack Obama calling Mahmoud Ahmadinejad. But wait! Is that a “Pssst…!”?

I immediately forwarded the newspaper to my face… It is a “Psst!”

I always thought that the Pssst is a Filipino trademark of informally calling the attention of your fellowmen.
Then I checked again:

Eh kaya naman pala eh! Si Kabayang Luis Vazquez naman pala ang cartoonist nila. Akala ko naman marunong nang sumutsot si Barack.
