This category of humor is a form of dark or gallows humor, which derives amusement from tragic, sensitive, or taboo subjects. The creation and reception of such content are often studied through theories of humor, such as the relief theory, which posits that laughter can release psychological tension built up by a traumatic event. Alternatively, incongruity theory suggests that the humor arises from the cognitive dissonance between the gravity of the 9/11 attacks and the trivial or absurd nature of a punchline. The passage of time is a critical factor in the social acceptability of this humor, as what is considered offensive shortly after a tragedy may become more permissible years later.
From a practical and sociocultural perspective, the phrase signifies a highly controversial form of expression. Its analysis reveals a tension between free speech and social sensitivity. For some, it serves as a coping mechanism or a way to subversively critique the official narratives surrounding the event. For others, particularly survivors and victims' families, it is deeply offensive and trivializes a national tragedy. Therefore, while its grammatical classification is straightforward, its use and interpretation are complex, involving ethical considerations and varying cultural or individual thresholds for what is considered acceptable humor.
