Subtle change turns McDonald's cup into huge controversy

Warning: This post contains a graphic drawing.

It's not the holiday season until someone is upset over a cup.

This time, McDonald's has come under fire for a seemingly harmless drink.

The container is covered in snowflakes, stars and some adorable mittens. It seems innocent, right?

With just a few squiggles, someone completely destroyed the sentimental value of the cup and turned it into something very NSFW.

Yep. Now it looks like a butt.
