Raj's bottom cream is a turn-off (8)
I believe the answer is:
junction
'a turn-off' is the definition.
(I've seen this before)
'raj's bottom cream' is the wordplay.
'bottom' suggests the final letters.
'cream' becomes 'unction' (unction can mean a cream or ointment).
The last letter of 'raj' is 'j'.
'j'+'unction'='JUNCTION'
'is' acts as a link.
(Other definitions for junction that I've seen before include "Point where ways meet" , "that may have box on either side" , "Where roads meet" , "meeting-place" , "Point of union" .)
