You’ll hear it in news reports, tech discussions, and even casual conversations online.
But the hijack meaning changes slightly depending on context.

In social media language, “hijack” can also mean taking over a conversation or trending topic, often in a humorous or strategic way.
This guide explains what hijack means, where it comes from, how it’s used today, and common misunderstandings clearly and simply.
