Slow movement is this, bar after bar (3-5)
I believe the answer is:
pub-crawl
'slow movement' is the definition.
'pub crawl' can be an answer for 'movement' (pub crawl is a kind of movement). I'm unsure of the 'slow' bit.
'is this bar after bar' is the wordplay.
'is this bar' becomes 'crawl' (I can't justify this - if you can you should believe this answer much more).
'after' is a charade indicator (letters next to each other).
'bar' becomes 'pub' (I've seen this before).
'crawl' put after 'pub' is 'PUB-CRAWL'.
Can you help me to learn more?
(Other definitions for pub-crawl that I've seen before include "Drinking expedition" , "Drinking session spread over several bars" , "Alcoholic journey" , "boozy event" , "Drinking tour" .)
