Cocky type later horsing around aboard boat (5,5)
I believe the answer is:
smart aleck
'cocky type' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'later horsing around aboard boat' is the wordplay.
'horsing around' is an anagram indicator (I've seen 'horses around' mean this).
'aboard' indicates putting letters inside.
'boat' becomes 'smack' (smack is a kind of sailing vessel).
'later' with letters rearranged gives 'rtale'.
'rtale' going into 'smack' is 'SMART-ALECK'.
Can you help me to learn more?
(Other definitions for smart aleck that I've seen before include "Upstart" , "Know-all" , "Wise guy" .)
