An anecdote or fact someone tells to make him/herself look like he/she actually knows something. Comes from Star Trek TOS, in which Ensign Pavel Chekov says that basically everything is a "Russian inwention" and why, leading to Kirk, in one episode whilst Sulu is launching into a complicated anecdote about Siberia, to announce that "if he wanted a Russian history lesson, he would have brought Mr. Chekov along".

Me: Please spare me the Russian history lesson.
You: (have just been owned)
