A "second story man" is someone who specializes in breaking into the upper levels of buildings to steal valuable items. While this phrase is commonly used, there are other synonyms that can be used to describe this type of criminal. One such term is a "cat burglar," which is derived from their ability to climb like a cat to access higher levels. Other synonyms include "climbing burglar," "high-rise thief," "elevated raider," and "rooftop burglar." These terms all convey the criminal's skill in accessing higher levels and stealing valuable items. Regardless of the term used, second story men pose a serious threat to any building's security and must be handled appropriately.
