You can see a longer video of Doris' hog-calling technique at the BBC.
I love this woman. Love. Her. Participating in a hog-calling contest requires rejecting just about everything that women are told they're supposed to be. You've got to be loud and zany and willing to contort your face and body into positions that might fairly be described as unattractive; you've got to be completely uninhibited, shameless, and out of control.
When a woman throws herself headlong into that sort of unselfconscious brazenness on a stage, I can't help but cheer.
And when it's a fat woman? Who knows damn well she'll weather eight gazillion "hog" jokes just for participating?
