means A rock genre built on crunchy guitars, big hooks, and sweet harmonies, trading rebellion for pure melodic pleasure.

from The term is usually credited to Pete Townshend of the Who, who used it around 1967 to describe his own band's sound — guitar-driven but melodic. It lay dormant until the mid-to-late 1970s, when bands like Big Star, the Raspberries, and Cheap Trick fused the energy of punk and British Invasion pop into something hook-heavy but tuneful, and critics revived Townshend's phrase to name it.
