Name given to a girl as a joke (5)
I believe the answer is:
sally
This clue is a triple definition!
'name' is the first definition.
'given' acts as a link.
'to a girl' is the second definition.
(girl's name)
'as' acts as a link.
'a joke' is the third definition.
(I've seen this in another clue)
(Other definitions for sally that I've seen before include "excursion" , "Rush out suddenly" , "Witty riposte" , "one in 3 the 12 30 [DROP the DEAD DONKEY]" , "Retort - Gracie Fields song" .)
