Bashful about a gee-gee being unkempt? (6)
I believe the answer is:
shaggy
'unkempt?' is the definition.
(I've seen this before)
'bashful about a gee-gee' is the wordplay.
'bashful' becomes 'shy' (bashful means shy or reserved).
'about' means one lot of letters goes inside another.
'gee' becomes 'g' (synonyms).
'gee' becomes 'g' (synonyms).
'a'+'g'+'g'='agg'
'shy' enclosing 'agg' is 'SHAGGY'.
'being' acts as a link.
(Other definitions for shaggy that I've seen before include "Kind of story about a dog?" , "Bushy" , "Hairy and unkempt" , "Scooby-Doo's friend" , "Rough-haired" .)
