Germany. Maybe I should qualify by saying that I don&#x27;t find &quot;fuck&quot; particularly offensive to begin with (American attitudes towards swearwords are strongly defined by its Puritan history).<p>There is a similar idiom in German (&quot;die Bombe platzen lassen&quot;, &quot;letting the bomb pop&quot;) but it has a different meaning (i.e. revealing shocking&#x2F;surprising information) and is different from how we refer to explosions (e.g. &quot;zünden&quot;, &quot;detonate&quot;) making it sound more like it&#x27;s describing a balloon than explosives.<p>I wonder why Americans consider &quot;fuck&quot; more offensive than other expletives, especially considering it&#x27;s so widely used (and in some social contexts wouldn&#x27;t raise any eyebrows at all). I guess it falls back to Puritanism again: not only is it a swearword, but it&#x27;s describing a sinful act -- not simply sexual intercourse but likely sexual intercourse in a very non-Puritan way (i.e. not soberly between a married faithful couple for purely reproductive purposes).<p>I should also add that English swearwords in German are generally far less offensive than the German equivalents, though even then they&#x27;re far more socially acceptable. I also think that the German equivalent of &quot;fuck&quot; as an expletive is actually borrowed from English and an artefact of the influence of English language media.<p>EDIT: I also find Puritanism far more appalling than any swearword or expletive.
