These are the ones I hate...

The people with the sunglasses hooked on the back of their t-shirt.  It looks ridiculous.  I don't get it.  These people come into my store all the time, and they are usually middle-aged men, or just twenty-something aged men who are waaaay too ready to be middle-aged, and they are wearing cargo shorts, and they have their fucking wrap-around shades hooked on the back of their stupid t-shirt.  I don't understand...  This does not seem functional, it seems hard to do, makes you look silly while you reach up and over your own shoulder just to retrieve your dumb sunglasses (because they invariably have bad taste in sunglasses), and blah, blah, blah...  I just hate them, that's all.
