Drink and drive into stuff (7)
I believe the answer is:
'stuff' is the 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 can't see?
'drink and drive' is the wordplay.
'drink' becomes 'grog' (grog is a kind of drink).
'and' means one lot of letters go next to another.
'drive' becomes 'ram' (RAM drive on a computer).
'into' acts as a link.
Can you help me to learn more?
(Other definitions for grogram that I've seen before include "fabric" , "Coarse material" , "Stuff that!" .)
