Dialectal Variation
British vs American Usage
Differences
Both share core meaning and extreme offensiveness. British usage may be more frequently heard in certain intense but non-literal exclamations (e.g., 'Fuck off!' expressing disbelief). Somewhat more likely to be used as a verb ('He fucked off to the pub') in British English.
Connotations
Universally recognized as one of the strongest possible insults/commands to depart. In both, it can signal the absolute end of a conversation or interaction.
Frequency
High frequency in very informal, confrontational, or 'laddish' speech cultures. Less frequent in public discourse due to its extreme nature.

- Confusing it with a less severe English phrase like 'back off' or 'buzz off'.
