Sausage crate (6)
I believe the answer is:
banger
This could be a double definition.
'sausage' is the first definition.
(banger is a kind of sausage)
'crate' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for banger that I've seen before include "Sausage (Inf)" , "Old and unreliable car" , "Sausage, firework and old car" , "It might just drive" , "Slangily, a noisy old car or a sausage" .)
