The world's new fastest texter is a 17-year-old physics student from Brazil, who upped his texting game after breaking his laptop in 2009 and depending entirely on his iPhone 3GS for survival.

Marcel Fernandes Filho beat out the previous Guinness World Record of 18.44 seconds—held, unsurprisingly, by another teen—ever so slightly, coming in at 18.19 seconds. The challenge requires typing long, complex sentences like this one: "The razor-toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality they seldom attack a human." The texting must be done both quickly and accurately, down to the punctuation. 

The whole thing reads as promotion for Fleksy, the flexible keyboard used by Filho, but we won't let that stop the teenager's shine.
