Bored, virtually carry out an unruly youth (10)
I believe the answer is:
perforated
'bored' is the definition.
(perforate can mean to bore a hole into)
'virtually carry out an unruly youth' is the wordplay.
'virtually' means to remove the last letter (all but the last letter).
'carry out' becomes 'perform' (performing is a kind of carrying out).
'an unruly youth' becomes 'ated' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'perform' with its last letter removed is 'perfor'.
'perfor'+'ated'='PERFORATED'
Can you help me to learn more?
(Other definitions for perforated that I've seen before include "ready to tear off" , "it's easy to pull off" , "Made holes in" , "Pierced like a sheet of stamps" , "prepared for tearing off a strip" .)
