Consumed in a threatening manner (5)
I believe the answer is:
eaten
'consumed' is the definition.
(similar in meaning)
'in a threatening manner' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EATEN' can be found hidden inside 'threatening manner'.
(Other definitions for eaten that I've seen before include "Gobbled" , "Polished off" , "dinners should be" , "having been fed?" , "What's taken in" .)
