Bachelor lounged about in club (8)
I believe the answer is:
'club' is the definition.
(both can mean a heavy weapon)
'bachelor lounged about' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'about' is an anagram indicator.
'lounged' with letters rearranged gives 'ludgeon'.
'in' is the link.
(Other definitions for bludgeon that I've seen before include "Club used maliciously" , "Thick stick as weapon" , "Stick or club with a heavy end" , "Strike with a club" , "(Beat with a) heavy stick" .)
