The term "cradle-robber" is considered derogatory and offensive, especially when used in reference to an older person dating or pursuing a younger individual. There are various synonyms that can be used to describe such behavior, including "pedophile," "predator," "sexual deviant," "pervert," and "exploiter." Other synonyms that may be used in a less negative and judgmental manner include "age-gap" relationship, "May-December" romance, or "intergenerational" relationship. It is important to choose language that is appropriate and respectful, while still clearly conveying the nature of the relationship in question.
