What does "to ninja" mean in internet slang?

It is used to describe posting or acting immediately before someone else in a thread, effectively superseding their response and making theirs look redundant or late. People typically say "Sorry, I think I ninja'd you" or "You ninja'd my answer" in forums, comment sections, or group chats when two users reply at nearly the same time. The term originated in early online forums and imageboards during the 2000s, drawing from the image of a fast, silent ninja striking before anyone notices.

Examples
He ninja'd my comment again in the thread.
