I guess I'm not a real man then. I have a number of pink shirts that I wear for work (amongst a whole load of other colours) and I've never even thought about my masculinity when wearing one. Frankly, the opposite seems to be true to me. If you have to put a big sign on your pink shirt talking about "real men" then you are pretty insecure about your pink shirt and your man status.
Bell also explained a second way to signal high-status: conspicuous outrage. Wear a shirt with the word "FUCK" on it in big letters (or, if you prefer, FCUK). This signals "I am so high status that I think I can wear the word 'FUCK' in big letters on a t-shirt and get away with it." It's a pretty good signal. It signals that you don't give a...well...fcuk what anyone else thinks, and the only people who would be able, either economically or psychologically, to get away with that are the high status
Is that a joke? High-status people wear shirts that say FCUK to show how high-status they are? Utter rubbish. The people who wear FCUK shirts (and other 'outrageous' designs) have nothing to do with high or low status. They are just being provocative, and I expect many, if challenged about what they were wearing would fail to be high-status about it.
