Pop her in pants for dance (8)
I believe the answer is:
hornpipe
'dance' is the definition.
(hornpipe is a kind of dance)
'pop her in pants' is the wordplay.
'pants' is an anagram indicator (UK informal term for 'nonsense' or 'rubbish').
'pop'+'her'+'in'='popherin'
'popherin' anagrammed gives 'HORNPIPE'.
'for' acts as a link.
(Other definitions for hornpipe that I've seen before include "Obsolete instrument: naval dance" , "Lively old sailors' dance" , "piece of music for an > old dance" , "Lively solo dance associated with sailors" , "Lively jig" .)
