Put out cigar and bonk Serpent (4,5)
I believe the answer is:
king cobra
'serpent' is the definition.
(I know that king cobra is a type of cobra)
'put out cigar and bonk' is the wordplay.
'put out' indicates anagramming the letters.
'and' means one lot of letters go next to another.
'cigar' after 'bonk' is 'bonkcigar'.
'bonkcigar' with letters rearranged gives 'KING COBRA'.
(Other definitions for king cobra that I've seen before include "Venomous type" , "Large venomous hooded snake" , "Large Asiatic snake" , "enormous snake" , "Hooded giant" .)
