'arrogant' is the definition.
(I've seen this before)

'elated ruth' is the wordplay.
'elated' becomes 'up' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ruth' becomes 'pity' (synonyms).
'up'+'pity'='UPPITY'

'and' is the link.

Can you help me to learn more?

(Other definitions for uppity that I've seen before include "Informally pert or arrogant" , "Not easily persuaded" , "Informally presumptuous or arrogant" , "Cheeky or presumptuous" , "Informally presumptuous or self-important" .)
