Drink from an odd sock? (3,5)
I believe the answer is:
rum punch
'drink' is the definition.
(thesaurus)
'an odd sock?' is the wordplay.
'an odd' becomes 'rum' (rum can mean strange or dubious).
'sock?' becomes 'punch' (I've seen this before).
'rum'+'punch'='RUM-PUNCH'
'from' acts as a link.
(Other definitions for rum punch that I've seen before include "old party special?" , "potential cause of merriment" .)
