Be too self-indulgent (7)
I believe the answer is:
overeat
'be' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for overeat that I've seen before include "Gorge oneself" , "Consume too much food, stuff your stomach" , "Binge" , "pig out?" , "ignore threat of a big corporation?" .)
