Differences
Both use it with the same core meaning. 'Fuck off' as a dismissive interjection ('Fuck off! You're joking!') may be slightly more common in UK speech. The adjectival use ('a fuck-off big truck') is strongly associated with British and Australian English.

FAQ
Frequently Asked Questions
Yes, but only among very close friends who have an established, jocular relationship where such taboo language is mutually understood as non-serious. The risk of causing offence is extremely high.
Yes. 'Fuck off' is generally considered the strongest and most direct of these vulgar 'go away' commands, due to the central taboo status of the word 'fuck'.
It is a phrasal verb (verb + particle). The imperative form is most common ('Fuck off!'). In reporting, it is used with verbs like 'tell' or 'say' ('He told me to fuck off').
Its offensiveness comes almost entirely from the word 'fuck', which remains one of the most powerful taboo words in English, associated with extreme violation of social decorum. The command itself is intentionally brusque and dismissive.
