'up' is the definition.
Both the definition and answer are adjectives.
Maybe they are linked in a way I don't understand?

'contemptible attention covering scottish garment being flipped' is the wordplay.
'contemptible attention' becomes 'ear' (having someone's ear is having their attention. I am not sure about the 'contemptible' bit.).
'covering' means one lot of letters goes inside another.
'scottish garment' becomes 'kilt' (I've seen this in another clue).
'being flipped' is a reversal indicator.
'ear' going around 'kilt' is 'ekiltar'.
'ekiltar' back-to-front is 'RATLIKE'.
