Georgia's brother picking up a streaker? (5)
I believe the answer is:
barer
'georgia's brother picking up a streaker?' is the definition.
I can't judge whether this definition defines the answer.
'brother picking up a streaker?' is the wordplay.
'brother' becomes 'br' (abbreviation in titles of monks).
'picking up' means one lot of letters goes inside another.
'a streaker?' becomes 'are' (I can't justify this - if you can you should believe this answer much more).
'br' placed around 'are' is 'BARER'.
Can you help me to learn more?
(Another definition for barer that I've seen is " Stripper".)
