It's not a guarantee, but if you engage in some version of what's commonly known as webspeak -- think acronyms gushing forth like alphabet soup and garbled phrases like "wat r u Sayg 2..me" -- you could end up on Failbook. If you attempt to communicate on the Internet with webspeak, and you know a whole bunch of Grammar Nazis who love to correct you, you've upped your chances of drawing out their indignation.
But woe betide the Grammar Nazi or otherwise judgmental person who makes a mistake in his or her comment critique! That's Failbook fodder for sure. If you scorn society (or just a friend's poor spelling), but make an error of your own in doing so, the crowd following Failbook will revel in the assumption that you're a perfect example of the silly masses (or, you know, same word without the "m").
But that's not the only trigger that can make fingers itch to submit your Facebook post to Failbook. Read on to learn more.
