Looking like a tourist eraser having a cuddle (13)
I believe the answer is:
rubbernecking
'looking like a tourist' is the definition.
I can't judge whether this defines the answer.
'eraser having a cuddle' is the wordplay.
'eraser' becomes 'rubber eraser' (rubber is a kind of eraser).
'having a cuddle' becomes 'necking' (I can't justify this - if you can you should give a lot more credence to this answer).
'rubber'+'necking'='RUBBERNECKING'
Can you help me to learn more?
(Other definitions for rubbernecking that I've seen before include "Stupidly looking at" , "Gawping" , "Gaping like a tourist" , "Nosily watching" .)
