I'm a little stuck... Click here to teach me more about this clue!

'burning' is the definition.
(similar in meaning)

I can't explain the rest of the clue.

(Other definitions for hot that I've seen before include "'Strike while the iron is ...'" , "Angry or very warm" , "Spicy or very warm" , "Under the collar, it means anger" , "Sultry in psychotic way" .)

I've seen this clue in the Evening Standard.
