I'm in the Philippines with my fiancee visiting her family for the Holidays. I decided to take a break from the festivities and browse BGG a bit. She comes in and sees one of the Tanga adds and asks if I know what that means. I give her my puzzled look and go "huh?"
"It means 'stupid' in Tagalog."
Sure enough, I check one of the pocket phrasebooks I brought along for the trip and find the following:
tanga ta-nga: idiot, stupid
Well, I better go back and be sociable, Maligayang Pasko! (that's Merry Christmas for all you non-Tagalog speakers )
