“I was about ten years old when we encountered a band of Cheyenne. They were on friendly terms with us, but we boys always indulged in sham fights on such occasions, and this time I got in an honest fight with a Cheyenne boy older than I. I got the best of the boy, but he hit me hard in the face several times, and my face was all spattered with blood and streaked where the paint had been washed away. The Sioux boys whooped and yelled: ‘His enemy is down, and his face is spattered as if with rain! Rain-in-the-Face! His name shall be Rain-in-the-Face!’”

— Rain-in-the-Face, from Charles Eastman’s 1918 book Indian Heroes and Great Chieftains
