People have already cleverly assigned sexual undertones to emoticons, so it's only natural that one porn company would use these "x-rated emojis" to let their customers choose what content they want to watch. Pornhub is that company. As though taking a note from Domino's pizza -- who let people order pizza using emojis -- this is a playful application.
The x-rated emoji pool is much more expansive than people could have imagined as well. The staples including a peach for big butts, eggplant for big penises and tongue for oral are obvious. But the octopus for hentai? And clashing swords for gay porn? That seems new.
How does it work? Just type in an x-rated emoji and you'll get a text back with a link to the chosen porn.
