A bit cheeky and not very friendly (6,4)
I believe the answer is:
rather cool
'a bit cheeky and not very friendly' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'bit cheeky and not very friendly' is the wordplay.
I cannot really see how this works, but
'bit' could be 'rather' (I have seen 'A bit' mean 'rather' so perhaps 'bit' could also mean 'rather') and 'rather' is present in the answer.
'not' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
The remaining letters 'col' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
