Travel, taking last bottle or bananas (9)
I believe the answer is:
globetrot
'travel' is the definition.
(globetroting is a kind of travelling)
'taking last bottle or bananas' is the wordplay.
'last' suggests the final letters.
'bananas' indicates anagramming the letters (bananas can informally mean crazy).
The last letter of 'taking' is 'g'.
'bottle'+'or'='bottleor'
'bottleor' is an anagram of 'lobetrot'.
'g'+'lobetrot'='GLOBETROT'
(Other definitions for globetrot that I've seen before include "travel widely" , "travel extensively" .)
