Trash-talking, defined as competitive incivility involving boastful comments or insulting remarks between opponents, is a common occurrence in workplaces, with a pilot study showing 57% of employees encountering it monthly or more. While it can motivate individuals to increase effort and performance on routine, effort-based tasks by increasing the psychological stakes of competition, it can be disruptive and diminish performance on creative tasks.

Researchers advise trash-talkers to consider the interpersonal consequences of their behavior, as they might unintentionally boost their opponent's motivation. Managers should strategically decide when to expose employees to trash-talking; it may be beneficial for routine tasks but detrimental for creative ones.

However, there's a crucial distinction between competitive incivility and harassment. Pranks or jokes that target protected characteristics like race, sex, religion, or disability are not mere jokes; they are harassment. Courts, as seen in cases like Banks v. GM, LLC, have consistently ruled that even a single incident of such conduct, like placing a noose, can create a severe hostile work environment, even if not every crude joke rises to that level.

Legal precedent indicates that jokes, especially political satire, are generally not considered grounds for defamation lawsuits, as reasonable listeners would not take them as statements of fact. Donald Trump's past threats to sue Trevor Noah over a joke and his defense of a joke about suing a Federal Reserve nominee illustrate this, with legal experts stating such defamation claims would be frivolous because a joke is not a statement of fact.
