'everywhere warming the bed' is the definition.
I can't judge whether this defines the answer.

'scorching latte brew to spill' is the wordplay.
'scorching' becomes 'hot' (similar in meaning).
'spill' indicates anagramming the letters (letters spilled or knocked around).
'latte'+'brew'+'to'='lattebrewto'
'lattebrewto' anagrammed gives 'waterbottle'.
'hot'+'waterbottle'='HOT-WATER BOTTLE'

Can you help me to learn more?
