Kim Kardashian announced that she will take Kanye West's last name as her own. She seemingly made this decision on the spot after a reporter asked her on the red carpet in Las Vegas. And she said no hyphen, because jeez, she already has a whole store called Dash. She'll just add West after Kardashian. This way, her moniker can expand ever onwards, into the far distance.
The women's Internet momentarily considered what this decision means from a feminist standpoint. Then they collectively decided, ehh. Let's just let this one go.
