Body odour is a social institution and we've been taught from a young age that it needs close and careful monitoring. And a man is a lot more worried than you think about carrying it about with him. She's a hard road, finding the perfect deodorant, boy.
Sometimes, in cheekily wearing yesterday's shirt, even after the application of initial-morning deodorant, the bad BO hits around early afternoon.
There is tacit agreement in the room that some man smells - and it's probably you. A man knows this and feels the sting of self-consciousness, shutting down his two underarm garages for the rest of the day to limit the stench.
This can only go so far, as everyone knows it's you. You've blundered in the eyes of the perfectionistic West again.
But to fold one's arms is the only mitigating factor available to a man, as adding deodorant will only exacerbate the slimy smell. Moreover, a mid-afternoon shower to a man, in the heat and the hum of summer, is a humiliating experience, so that option is off-limits. I don't know for sure why. Anyway, the damage has been done.
