pulling a pepsi
When you royally screw up by trying to advocate something unpopular and at the same time use unpopular objects in your argument. In the end, you just make a fool of yourself and what your trying to advocate.
Pepsi really outdid themselves by pulling a pepsi when they aired an ad about the black-lives matter movement and also included Kendall Jenner. This all ended in a fail, resulting in backlash.
