I gave an involuntary bark of laughter. I'm sorry, but I don't think I've ever heard the MCX called the "Black Mamba", not even in a video game."(T)he MCX is known in military circles as the "Black Mamba"" -Mother Jones is where I go for all my gun facts!https://t.co/yGtnDAD3yU— Tamara K.

I'm not sure whether this is an example of Argumentum ad anus extractus, which is the logical fallacy of pulling stuff out of your ass, or Argumentum ad feces fabricatum, which is argument by making shit up.
ETA: I've been informed by friends that it was in inside term during project development because the black mamba is the bane of the honey badger. I'll contend that that's still a pretty big jump to "known in military circles".
