Ghostface Chillah Snapchat Snapchat is continuing to take the digital world by storm, making its yellow-ghost icon a ubiquitous symbol.

So who is that cute little ghost with his tongue sticking out? Well, his name is Ghostface Chillah.

"He's a silly dude," Snapchat CEO Evan Spiegel told Business Insider in a recent interview. Spiegel drew the icon himself.

Spiegel says he was into rap for a long time and the icon was ultimately inspired by the Wu-Tang Clan rapper Ghostface Killah.

Facebook CEO Mark Zuckerberg also got personally involved in building his copycat app called Poke. While he didn't draw the app's icon, he recorded the "poke" sound.
