Be repulsive as you stagger round the piano (5)

I believe the answer is:
repel
'be repulsive as' is the definition.
I can't judge whether this definition defines the answer.
'stagger round the piano' is the wordplay.
'stagger' becomes 'reel' (both can mean to move around without balance).
'round' is an insertion indicator.
'the piano' becomes 'p' (musical abbreviation).
'reel' enclosing 'p' is 'REPEL'.
'you' is the link.
Can you help me to learn more?
(Other definitions for repel that I've seen before include "Nauseate" , "Sicken" , "Parry" , "push off" , "Drive back or ward off" .)
