Dialectal Variation
British vs American Usage
Differences
The literal basketball term is equally understood due to global sports media. The figurative sense is understood but less frequently used in UK English, where terms like "dead cert", "sure-fire winner", or "foregone conclusion" are more idiomatic.
Connotations
US: Strongly positive, implying power and certainty. UK: May be perceived as an Americanism; when used, it retains the positive connotation but may sound consciously informal or imported.
Frequency
Much higher frequency in American English across all contexts. In UK English, usage is largely confined to business/politics reporting and is more common in written media than spontaneous speech.
