'without thought' is the definition.
I can't judge whether this defines the answer.

'australian male wild cat consumed one' is the wordplay.
'australian' becomes 'au'.
'male' becomes 'tom' (tom can mean a male cat).
'wild' is an anagram indicator.
'consumed' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'cat' with letters rearranged gives 'atc'.
'atc' going around 'i' is 'atic'.
'au'+'tom'+'atic'='AUTOMATIC'
