Drink out of 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'
'out of' acts as a link.
(Other definitions for rum punch that I've seen before include "potential cause of merriment" , "old party special?" .)
