Say Oscar first in command, being self-obsessed (8)

Ross

I believe the answer is:

egoistic

I'm a little stuck... Click here to teach me more about this clue!

'self-obsessed' is the definition.
I can't tell whether this defines the answer.

'say oscar first in command' is the wordplay.
'say' becomes 'eg' (both can mean 'for example').
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
'first' becomes 'ist' (ist resembles 1st).
'in command' becomes 'ic' (military abbreviation).
'eg'+'o'+'ist'+'ic'='EGOISTIC'

'being' is the link.

Can you help me to learn more?

(Other definitions for egoistic that I've seen before include "Self-important" , "self-seeking" , "Displaying self-regard" , "Self-absorbed" , "Full of oneself" .)
