A dance or a dip (5)
I believe the answer is:
salsa
This clue is a double definition.
'a dance' is the first definition.
(type of dance)
'a dip' is the second definition.
(I've seen this before)
(Other definitions for salsa that I've seen before include "fling?" , "dancing?" , "Saucy dance" , "Dance or a dip?" , "Spicy tomato sauce" .)
