Gets out for a bit of fun with the chaps (5)
I believe the answer is:
gents
'chaps' is the definition.
('gent' can be a synonym of 'chap')
'gets out for a bit of' is the wordplay.
'out' is an insertion indicator.
'for a bit of' becomes 'n' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gets' enclosing 'n' is 'GENTS'.
'fun with the' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for gents that I've seen before include "toilet" , "Public convenience" , "Men (colloq.)" , "Male loos" .)
