SHE is Australia's obscene beauty queen, a surreal showgirl and a feminist clown.
Grumble is Gibson's alter ego, a performer of grotesque burlesque and the ultimate triple threat.
"She is in defiance of drudgery and the tyranny of the familiar," Gibson said.
"I think Betty Grumble has a message which comes from a place of love and anger towards the state of the world and women being the second sex."
Gibson came to burlesque from a dance and drama background, having discovered performance art while at university.
"I was exploring what it means to be a woman body on stage," she said.
"I come from a family of comedians, my aunt Lynda Gibson inspired me to use comedy as a way of thinking about the world."
Gibson said her performance activism jelled well with the show Frida People.
"It is about bringing the people a very necessary, political and love-feel show," she said.
It will combine poetry, funk and soul-inspired music, and of course grotesque burlesque.
