In Kabul generally one gets the hump (5)
I believe the answer is:
bulge
'the hump' is the definition.
('bulge' can be a synonym of 'hump')
'in kabul generally one' is the wordplay.
'in' indicates a hidden word.
'BULGE' is hidden in the letters of 'kabul generally one'.
'gets' acts as a link.
(Other definitions for bulge that I've seen before include "Protuberance or outward swelling" , "Hump" , "Protrude" , "surge?" , "Rounded swelling" .)
