Usage

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 These senses of the word can sound a bit outdated.Rocker is also used in the phrase off one’s rocker, which means about the same thing as out of one’s minddelusional or completely irrational.Example: It’s a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!
