Stupidly tries to get round me, which is aggravating (8)
I believe the answer is:
tiresome
'is aggravating' is the definition.
(I've seen this before)
'stupidly tries to get round me' is the wordplay.
'stupidly' is an anagram indicator (a stupid ordering of the letters).
'to get round' becomes 'o' (I've seen this in other clues).
'tries' is an anagram of 'tires'.
'tires'+'o'+'me'='TIRESOME'
'which' is the link.
(Other definitions for tiresome that I've seen before include "Tedious and boring" , "Aggravating" , "Wearying" , "Draggy - unamusing" , "Boring, annoying" .)
