Bold, be a nuisance around friend (3,4)
I believe the answer is:
old bean
'friend' is the definition.
(I've seen this before)
'bold be a nuisance around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'OLD BEAN' can be found hidden inside 'bold be a nuisance'.
(Other definitions for old bean that I've seen before include "Term of affection for a man" , "Good friend" , "Affectionate form of address to a man" , "Familiar way to address" , "Dated familiar term of address to a man" .)
