Called me in and exploded (5)
I believe the answer is:
named
'called' is the definition.
(synonyms)
'me in and exploded' is the wordplay.
'in' means one lot of letters goes inside another.
'exploded' indicates anagramming the letters.
'and' with letters rearranged gives 'nad'.
'me' inserted within 'nad' is 'NAMED'.
(Other definitions for named that I've seen before include "Entitled" , "Christened" , "Called" , "Designated" , "Handled" .)
