English overwhelms us with options, thanks partly to its abundance of vulgarisms. If I call you a “wanker” I mean something subtly different from a “dickhead”. (It can be hard to pinpoint these nuances without resort to further swearing, as demonstrated by users of urbandictionary.com, as they struggle to define a “prick“: “An all around fucktard, dickweed, assrat bastard.”) These differences aren’t just a matter of intensity. We can presumably all agree that Simon Cowell is a bit of a tosser. But his success makes it hard to dismiss him as a fuckwit, while it’s not clear he’s guilty of the malice that would condemn him as a shit.
