Bull (as in nonsense) is the definition. Four letter word for squeezed as in extorted + outside of Unionist all inside a word for shower, jet of water without the last letter
Thanks Quisling for the help. Even with your parsing it took sometime to get the correct answer. Hearing this idiom for the first time. Learnt a new word/idiom.
Tricky. The definition is anxiety. Reversal (on the rise) of a four-letter word for fresh, saucy, followed by an eight-letter word for the ability to form images dropping the letter “e” (limit of couple)
