What does rocker mean?

A rocker is a type of cradle for babies that’s used to gently rock them from side to side to calm them down or get them to fall asleep. It should not be confused with a bouncer, which is a kind of seat that allows older babies to stand up and bounce up and down.

Rocker can also be used as another name for a rocking chair, or one of the two curved pieces on which it sits that allow it to rock back and forth. Such pieces are also found on other kinds of furniture, such as cradles. They can also be called runners.

Rocker can refer to a rock musician, a fan of rock music, or a rock song that especially rocks (meaning it’s an intense example of the hard-driving beat and other qualities associated with rock music, all turned up to 11). These senses of the word can sound a bit outdated.

Rocker is also used in the phrase off one’s rocker, which means about the same thing as out of one’s minddelusional or completely irrational.

Example: It’s a miracle how well this rocker works at getting my baby to calm down—thanks, Lemmy!

Where does rocker come from?

The first records of the word rocker come from around the 1400s in reference to someone who rocks a cradle. Today, a lot of baby rockers are electronic and do the rocking automatically.

By the late 1700s, rocker was being used to refer to one of the curved pieces of wood on a cradle, chair, or rocking horse. Rocker came to be used in reference to a rocking chair in the 1800s.

The first records of rocker pertaining to rock music and rock stars come from the 1940s. These senses of the word come from the original name of the genre: rock-’n’-roll. In the late 1950s and the 1960s, the word started to be used to refer to fans of rock music, especially in categories of subculture members divided by fashion and musical taste, including rockers, mods, and punks. Today, a rock musician is much more likely to be called a rock star than a rocker. One exception is the use of the term rocker in the term punk rocker, which can refer to a punk rock musician or fan, as in Sheena is a punk rocker.
