Sways like drunk in fast dance with son (5)
I believe the answer is:
reels
'sways like drunk in fast' is the definition.
'reels' can be an answer for 'sways' (I've seen this in another clue). I'm not certain of the 'like drunk in fast' bit.
'dance with son' is the wordplay.
'dance' becomes 'reel' (reel is a kind of dance).
'with' is a charade indicator (letters next to each other).
'son' becomes 's' (genealogical abbreviation for son).
'reel'+'s'='REELS'
Can you help me to learn more?
(Other definitions for reels that I've seen before include "Bobbins" , "performed by dancers" , "Rolls of film and dances" , "Cylinders on which cords are wound" , "Scottish dances" .)
