"Button man" is a term that's commonly associated with organized crime and gangsters. It refers to a hired thug or an enforcer who's tasked with carrying out acts of violence or intimidation on behalf of their boss or organization. However, there are several other synonyms that can be used to describe such individuals. These include "enforcer", "muscle", "torpedo", "hitman", "heavy", "hatchet man", "soldier", "thug", and "strong-arm". While these terms may sound glamorous or intriguing in works of fiction, it's important to remember that real-life violence can have severe and lasting consequences. As such, it's crucial to avoid glorifying or romanticizing the use of force and coercion in any context.
