What is the meaning of this?

Burger King is using sex to sell their stale Kids Meals to your little ones.

The Square Butts Burger King music video, featuring the creepy crowned dude from the BK commercials and Nickelodeon’s own SpongeBob Squarepants, just hit the Internet. Sure to become a viral hit, the new campaign was inspired by Sir Mix-a-Lot’s 1991 hit, “Baby Got Back.”

Are they selling burgers or boy shorts?
