Name-dropping is the practice of naming or alluding to important people and institutions within a conversation,story,song, online identity, or other communication. The term often connotes an attempt to impress others; it is usually regarded negatively, and under certain circumstances may constitute a breach of professional ethics. When used as part of a logical argument it can be an example of the false authority fallacy.
A 'shout-out' is a type of name-dropping where someone's name, or a list of names, is spoken out in order to direct attention towards these groups or individuals, often as a means of expressing or making a referral.
American essayist Joseph Epstein defines name dropping as follows :
name-dropping [...] is using the magic that adheres to the names of celebrated people to establish one's superiority while at the same time making the next person feel the drabness of his or her own life. Name-dropping is a division of snobbery, and one of the snob's missions is to encourage a feeling however vague of hopelessness in others.
Name-dropping is used to position oneself within a social hierarchy. It is often used to create a sense of superiority by raising one's status. By implying (or directly asserting) a connection to people of high status, the name-dropper hopes to raise his or her own social status to a level closer to that of those whose names he or she has dropped, and thus elevate himself or herself above, or into, present company.
Name-dropping can also be used to identify people with a common bond. By indicating the names of people one knows, one makes known his or her social circle, providing an opportunity for others with similar connections to relate.
As a form of appeal to authority, name-dropping can be an important form of informal argumentation, as long as the name being dropped is of someone who is an expert on the subject of the argument and that person's views are accurately represented.
