Hell, damn and bitch are especially popular in the south and southeast. Douche is relatively common in northern states. Bastard is beloved in Maine and New Hampshire, and those states – together with a band across southern Arizona, New Mexico, and Texas – are the areas of particular motherfucker favour. Crap is more popular inland, fuck along the coasts. Fuckboy – a rising star* – is also mainly a coastal thing, so far.
Who knew?
