I didn't quite get that dance (6-2)
I believe the answer is:
excuse-me
I believe this is a double definition.
'i didn't quite get that' is the first definition.
('excuse me' means I didn't catch what you said)
'dance' is the second definition.
(I've seen this before)
(Other definitions for excuse-me that I've seen before include "Dance where partners swapped" , "Phrase to catch attention or apologise" , "Sort of dance - apology" , "Apology for breaking in - dance" , "Dance during which one changes partners" .)
