When you go out of your way to purchase all the cars your friends and family own, so when they come down, you force them to try it out on your steering wheel (Logitech G27) to confirm how much better it feels than the real deal and stand back looking smug with a smug grin whilst dropping the full name of the wheel (ahem, Logitech G27) into every other sentence.
"How's that feel? Feels good, huh? You like it, don't you? Feels real, don't it? Yeah, got the Logitech G27 on sale, 169 quid, you should get one, mind you, it's gone up now, yeah, 200 quid, shame."
Not forgetting to add, you plan on upgrading to a Thrustmaster T500RS and its gear shift TH8RS, mentioning how much it costs and how the shifter isn't included in the price, also adding how some setups can cost grands, then pulling out your phone to show YouTube videos of some crazy rigs starting with the one on hydraulics, you know the one. Then dropping your voice into a low growl and saying "I'm Batman". I'll stop now.
