'south african' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'philosophy club untucked trousers' is the wordplay.
'trousers' says the answer is hidden in the clue (trouser can mean to steal or take).
'UBUNTU' is hidden in the letters of 'philosophy club untucked'.

(Other definitions for ubuntu that I've seen before include "Humanity in Cape" , "humanity in South Africa" .)
