Living overseas, she can text without Dad losing head (5)
I believe the answer is:
expat
'living overseas' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'she can text without dad losing head' is the wordplay.
I cannot really see how this works, but
'she' could be 'pat' and 'pat' is found within the answer.
'without' could be 'ex' (I've seen this in other clues) and 'ex' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for expat that I've seen before include "Former countryman" , "Person living abroad" , "he has emigrated" , "One who lives abroad" , "Degrade" .)
