Shapps ignoring last two flipping expressions of contempt (4)

I believe the answer is:

pahs

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

'expressions of contempt' is the definition.
'pahs' can be an answer for 'expressions' (I have seen 'dismissive expressions' mean 'pahs' so perhaps 'expressions' could also mean 'pahs'). I am unsure of the 'of contempt' bit.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for pahs that I've seen before include "Settlements" , "dismissive expressions" , "expressions of disgust" .)

I've seen this clue in The Independent.
