Cardi B Selling Wet-Themed 'WAP' Merchandise Like Umbrellas and Ponchos

Cardi B's not wet behind the ears when it comes to promoting herself, so it's no surprise she's selling "WAP" gear in a way that'll get everyone talking.

The rapper's online store is promoting a new merchandise line featuring the title of her sexually explicit hit track with Megan Thee Stallion, and it's um ... water-themed.

To make sure her fans don't get soaked, Cardi's got "WAP" umbrellas, rain ponchos, spandex sports bras and biker shorts for sale.

There's also "WAP" t-shirts, sweatshirts, sweatpants and crop-top hoodies available ... and some of the attire features sexy shots of Cardi and Meg.

If you've been living under a rock, you might not know that the duo's hit track has been all the rage since the release of the music video -- which features a Kylie Jenner cameo -- earlier this month.
