Got date and ain't bothered! (8)
I believe the answer is:
attained
'got' is the definition.
(attaining is a kind of getting)
'date and ain't bothered' is the wordplay.
'and' means one lot of letters go next to another (I've seen this in other clues).
'bothered' is an anagram indicator.
'date' after 'aint' is 'aintdate'.
'aintdate' anagrammed gives 'ATTAINED'.
(Other definitions for attained that I've seen before include "Reached a goal" , "Accomplished, achieved" , "Reached (eg, age)" , "Reached with effort" .)
