Consumed by passion on the dance floor, beau ultimately put off (10)
I believe the answer is:
discourage
'put off' is the definition.
(I've seen this before)
'consumed by passion on the dance floor beau ultimately' is the wordplay.
'consumed by' means one lot of letters goes inside another (I've seen this in other clues).
'passion' becomes 'rage' (synonyms).
'on' means one lot of letters go next to another.
'the dance floor' becomes 'disco'.
'ultimately' suggests the final letters.
The final letter of 'beau' is 'u'.
'rage' put after 'disco' is 'discorage'.
'discorage' enclosing 'u' is 'DISCOURAGE'.
(Other definitions for discourage that I've seen before include "Try to stop" , "Talk out of" , "Deter; dishearten" , "Cause loss of enthusiasm in (someone)" , "Put off" .)
