Macho - some jerkwad wearing snakeskin cowboy boots, tight boot-cut jeans, tailored long-sleeve button shirt, handlebar moustache, and a cowboy hat, molesting some woman in a dimly lit, smoke-filled bar.
"Macho" to me means ego uber alles, and that pretty much describes most duded up city "cowboys" I've ever met, so that's the image that comes to mind first.
