Sort hating bumpy fairground ride (5,5)
I believe the answer is:
ghost train
'fairground ride' is the definition.
(I know that ghost train is a type of fairground ride)
'sort hating bumpy' is the wordplay.
'bumpy' indicates anagramming the letters (letters get bumped around).
'sort'+'hating'='sorthating'
'sorthating' is an anagram of 'GHOST-TRAIN'.
(Other definitions for ghost train that I've seen before include "scary ride" , "funfair ride" , "Fairground attraction" , "Spooky ride" .)
