Frequency
Moderately common in both, slightly more frequent in US media, especially sports commentary.

Memory Aids
Mnemonic
Imagine a poker glowing RED because it's so HOT – that's the core meaning. Now imagine a news story or a sports team generating that same level of intense heat and colour – that's the extended meaning.
Conceptual Metaphor
INTENSITY IS HEAT; POPULARITY/FRESHNESS IS HEAT.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'красно-горячий' – not idiomatic. For literal heat, use 'раскалённый докрасна'. For metaphorical intensity, consider 'невероятно популярный', 'на пике популярности', 'горячий' (e.g., горячая новость).
Common Mistakes
- Using it as a predicate without hyphen ('The metal was red hot') – standard spelling requires hyphen in attributive position ('a red-hot poker') but often accepted without hyphen in predicate. Confusing with 'white-hot' (even hotter). Overusing for mild popularity.
