'matey' is the definition.
Both the answer and definition are adjectives.
Maybe you can see a link between them that I can't see?

'obelisk rough and hard' is the wordplay.
'rough' is an anagram indicator (a rough or broken ordering of the letters).
'and' is a charade indicator (letters next to each other).
'hard' becomes 'h' (abbreviation used in pencil classifications).
'obelisk' anagrammed gives 'blokeis'.
'blokeis'+'h'='BLOKEISH'
