Load of cool blokes in street (8)
I believe the answer is:
shipment
'load' is the definition.
(I know that load can be written as shipment)
'cool blokes in street' is the wordplay.
'cool' becomes 'hip' (hip can mean cool or fashionable).
'blokes' becomes 'men' (bloke can informally mean a man).
'in' means one lot of letters goes inside another.
'street' becomes 'st' (abbreviation).
'hip'+'men'='hipmen'
'hipmen' inserted within 'st' is 'SHIPMENT'.
'of' is the link.
(Other definitions for shipment that I've seen before include "Consignment of goods" , "A consignment as for marine transport" , "load" , "22 [CARGO]" .)
