The term "Q" is often associated with the QAnon conspiracy theory, which emerged in late 2017. QAnon alleges that there is a secret plot against President Donald Trump by a deep state of global elites involved in child trafficking, satanic rituals, and other nefarious activities.

In the context of QAnon, "Q" refers to an anonymous online person or group of people who claimed to have insider knowledge of this conspiracy and posted cryptic messages on internet forums, primarily 4chan and later 8chan/8kun. These messages, known as "Q drops," often contained predictions or hints about future events.

It's important to note that the claims made by QAnon are baseless and have been debunked by numerous credible sources. The identity of "Q" remains unknown, and there is no evidence to support the validity of the conspiracy theory. QAnon has been widely criticized for promoting false information, causing harm to individuals, and contributing to the spread of disinformation.
