Blue tick’s lost? Start to tweet series of unsatisfied experiences (6,4)
I believe the answer is:
bucket list
'tweet series of unsatisfied experiences' is the definition.
The definition suggests a singular noun which matches the answer.
'blue tick's lost? start to' is the wordplay.
'lost?' indicates anagramming the letters.
'start' says to take the initial letters.
The first letter of 'to' is 't'.
'blue'+'ticks'='blueticks'
'blueticks' anagrammed gives 'bucketlis'.
'bucketlis'+'t'='BUCKET LIST'
Can you help me to learn more?
(Another definition for bucket list that I've seen is " Things to do before kicking it?".)
