Wouldn't ascertain as to whether I'm referring to real life or gaming when I say "That shot could've come from that grassy knoll!"
False. Gaming takes place in real life, and in reality people play games and say things about knolls and shots that are fired therein. In the case of your life outside of playing a game, since you are a serviceman, it's entirely possible you uttered that phrase in your line of work as well, which would of course be a real life action.
My guess would be that Rockingham takes the internet and forums way too seriously.
