kiss my ass

Robert B.Parkerの "Painted Ladies"を読むことにしました。Robert B.Parkerの作品は7年前に "Wilderness" を読んでいるので、２作品目です。

A group of pigeons was pecking at some popcorn that had been thrown on the ground for them. Pearl chased them off and ate the popcorn. A mature woman in a leopard-skin coat stood up from the bench where the pigeons had gathered and walked toward us.
"Madam," she said, "control your dog. That popcorn is intended for the pigeons."
Susan smiled.
"Survival of the fittest," she said.
The woman frowned.
She said, "Don't be flippant, young woman."
"Yikes," I murmured.
Susan turned slowly toward the woman.
"Oh, kiss my ass," Susan said.
The woman took a half step back. Her face reddened.
She opened her mouth, and closed it, and turned and marched away.
