I believe the answer is:
tango
'dance that takes two' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tango that I've seen before include "one followed by uniform" , "Latin American dance takes two to do it" , "something seen in ballroom?" , "Tonga (anag.)" , "Latin American dance (requiring two?)" .)
