Buck bet on pole dancing (8)
I believe the answer is:
antelope
'buck' is the definition.
(thesaurus)
'bet on pole dancing' is the wordplay.
'bet on' becomes 'ante' (anteing is a kind of betting on).
'dancing' is an anagram indicator.
'pole' anagrammed gives 'lope'.
'ante'+'lope'='ANTELOPE'
(Other definitions for antelope that I've seen before include "One leapt badly on the graceful animal" , "Reebok perhaps" , "One ruminating" , "Springbok or gnu?" , "fast buck, perhaps?" .)
