A "drop dead list" can also be referred to as a "blacklist" or "ban list." It is a list of people or things that are not welcome or allowed in a certain place or situation. Other synonyms for this term include "exclusion list," "taboo list," and "denial list." In a professional setting, it can also be called a "termination list" or "dismissal list." This type of list is commonly used for security, safety, and compliance purposes. Whatever the name, it presents a clear message that those on the list are not to be included or tolerated in a given context.
