"I’m sick of the PC bullshit we see all over the news shows these days. When you first saw this story all of the beautiful anchors would say the same thing: “This woman, Susan Boyle, a person you might not expect, just blew everyone’s minds with her rendition of blah blah blah.” Let’s look at the phrase in question here. “A person you might not expect.” Short for U.A.F.
Ugly. As. Fuck."
