Earlier this week, the official PlayStation UK account tweeted out something that seemingly rocked the gaming community. It turns out, that “X” button (commonly pronounced “ex”) on the right side of the PlayStation Dualshock controller is actually called the “Cross” button, as reported by Eurogamer.

"Triangle. Circle. Cross. Square," PlayStation UK tweeted. "If Cross is called X (it's not), then what are you calling Circle?"

PlayStation UK even took a moment to poke fun at those who call it “ex” with a classic SpongeBob meme.

Other Twitter users chimed in to offer their takes, scientific or otherwise.

And apparently we’re all just plain wrong, if PlayStation’s engineers have anything to do with it.

So what do you call the southernmost face button on the Dualshock controller? Is PlayStation living a lie or the final word on the matter? Sound off in the comments, or check out our favorite PS4 controllers.
