Opinion of pair as lap dancing (9)
I believe the answer is:
appraisal
'opinion' is the definition.
(thesaurus)
'pair as lap dancing' is the wordplay.
'dancing' indicates anagramming the letters.
'pair'+'as'+'lap'='pairaslap'
'pairaslap' anagrammed gives 'APPRAISAL'.
'of' is the link.
(Other definitions for appraisal that I've seen before include "valuation" , "judgment" , "rating" , "Formal assessment of an employee's performance" , "Evaluation - price survey" .)
