“Competing folk etymologies circulate — that it mocked hair-metal's crotch/butt-thrusting stage antics, that it came from radio slogans like "we play nothing but rock" ("but rock"), or that it's simply "butt" as a synonym for bad — and I don't know of solid lexicographic evidence settling which came first.”
