My knickers in a twist seeing this grid's offensive entries? (6,5)

'a twist seeing this grid's offensive entries?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'my knickers' is the wordplay.
I cannot quite understand how this works, but
'my' could be 'cor' (both are expressions of surprise) and 'cor' is located in the answer.
an anagram of 'knickers' is 'nerkicks' which is within the answer.
No letters remain.
This explanation may well be incorrect...

'in' acts as a link.

Can you help me to learn more?
