Stagger around belching, primarily -- one's revolting (5)
I believe the answer is:
rebel
'one's revolting' is the definition.
I can't judge whether this defines the answer.
'stagger around belching primarily' is the wordplay.
'stagger' becomes 'reel' (both can mean to move around without balance).
'around' indicates putting letters inside.
'primarily' indicates taking the first letters.
The first letter of 'belching' is 'b'.
'reel' going around 'b' is 'REBEL'.
Can you help me to learn more?
(Other definitions for rebel that I've seen before include "One resisting authority" , "Freedom fighter?" , "Rise in armed opposition" , "Anti-establishment figure" , "Insurgent, renegade" .)
