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 can't judge whether it can be defined by this definition.

'my knickers' is the wordplay.
I cannot quite see 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 present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'in' is the link.

Can you help me to learn more?
