Turning excited on cocaine, gets into fight in bar tour (3,5)
I believe the answer is:
pub crawl
'fight in bar tour' is the definition.
'pub crawl' can be an answer for 'tour' (pub crawl is a kind of tour). I am not certain of the 'fight in bar' bit.
'turning excited on cocaine gets' is the wordplay.
'turning' says the letters should be written in reverse.
'excited' becomes 'up'.
'on' is an insertion indicator (as in clothing 'on' a person).
'cocaine' becomes 'C' (drugs abbreviation).
'gets' becomes 'brawl' (I can't explain this - if you can you should give a lot more credence to this answer).
'up' back-to-front is 'pu'.
'c' placed into 'brawl' is 'bcrawl'.
'pu'+'bcrawl'='PUB-CRAWL'
'into' acts as a link.
Can you help me to learn more?
(Other definitions for pub crawl that I've seen before include "Local tour" , "A local expedition?" , "Drinking session spread over several bars" , "social event" , "Bender" .)
