Terrible pimp last week in your day of penitence? (3,6)
I believe the answer is:
yom kippur
'day of penitence?' is the definition.
'terrible pimp last week in your' is the wordplay.
'terrible' indicates anagramming the letters.
'last' suggests the final letters.
'in' indicates putting letters inside.
The last letter of 'week' is 'k'.
'pimp'+'k'='pimpk'
'pimpk' with letters rearranged gives 'mkipp'.
'mkipp' inserted inside 'your' is 'YOM KIPPUR'.
Can you help me to learn more?
(Other definitions for yom kippur that I've seen before include "Jewish solelmn Day of Atonement" , "Jewish Day of Atonement, most solemn of the year" , "Religious fast" , "Jewish holy day" , "'Day of Atonement for Jews (3,6)'" .)
