The cleric said Indonesian President Susilo Bambang Yudhoyono, widely known by his initials SBY, is an unbeliever because of his “failure to hold up the true law under Islam,” Indonesian English-language newspaper the Jakarta Post reported Monday.

SBY is a popular president in his second term, and a Muslim. The rabble-rousing cleric, Abu Bakar Ba’asyir, also said all Indonesian leaders were evil, but that Islam had been especially slandered under SBY’s presidency.

The Indonesian Twittersphere immediately reacted to the cleric’s accusation, using the words‘SBY Kafir’ to talk about it, which translates to ‘SBY infidel.’

Most tweets from Indonesia were words in support of the president, clarifying that he is not “kafir”:

SBY is NOT kafir. I mean, come ON, you can’t do that to our president. :lless than a minute ago via Twitter for BlackBerry® Favorite Retweet ReplyRianna Lauren

But it was also a lesson in subjects that take on a life of their own on the Internet, as many tweeted for “SBY Kafir” to stop trending, but perpetuated its use by doing so:
