Corrupt monster having friendly relations (2,5)

Ross

I believe the answer is:

on terms

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

'friendly relations' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'corrupt monster' is the wordplay.
'corrupt' is an anagram indicator (a corrupted form).
'monster' is an anagram of 'ON TERMS'.

'having' is the link.

Can you help me to learn more?

(Another definition for on terms that I've seen is " Monster (anag) - level in score".)

I've seen this clue in The Independent.
