I’m impatient and always drink to stay bluff (3,8,4)
I believe the answer is:
for goodness sake
'irsquom impatient' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'always drink to stay bluff' is the wordplay.
'always' becomes 'forgood' (for good can mean permanently or forever).
'drink' becomes 'sake' (sake is a kind of drink).
'to stay' means one lot of letters goes inside another (stay can mean to restrain or control).
'bluff' becomes 'ness' (both can mean a cliff or promontory).
'forgood'+'sake'='forgoodsake'
'forgoodsake' enclosing 'ness' is 'FOR GOODNESS SAKE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for for goodness sake that I've seen before include "Really!" , "please!" , "Words of exasperation" .)
