What's given to yobs? Spirits, lagers, wine (5,5,5)
I believe the answer is:
short sharp shock
'what's given to yobs?' is the definition.
(Thatcher policy)
'spirits lagers wine' is the wordplay.
'spirits' becomes 'shorts' (short can mean a drink of spirits).
'lagers' becomes 'harps' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'wine' becomes 'hock' (hock is a kind of wine).
'shorts'+'harps'+'hock'='SHORT SHARP SHOCK'
Can you help me to learn more?
(Other definitions for short sharp shock that I've seen before include "Correction" , "Number one cut, with gel" .)
