When you see a guy at work wearing a M track suit, M pants, a M hat, and M gloves
So you say, innocently enough, since the guy is like a walking M mascot, "wow, you must really love BMW M, which M car do you have?"
And he gives you a insulted look and says, "I don't have a M-car, I have a regular BMW"
And now it's a bit awkward so you just say "oh, OK then"
