Informal artist given gibe that's degrading (5,3)

Ross

I believe the answer is:

infra dig

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

'that's degrading' is the definition.
(I've seen this before)

'informal artist given gibe' is the wordplay.
'informal artist given' becomes 'infra' (I can't explain this - if you can you should believe this answer much more).
'gibe' becomes 'dig' (synonyms).
'infra'+'dig'='INFRA-DIG'

Can you help me to learn more?

(Other definitions for infra dig that I've seen before include "Rigid fan may be lacking in dignity" , "Such as one would not stoop to" , "Demeaning (Latin)" , "Beneath one" , "degrading" .)
