Stick around for a drink perhaps (3)
I believe the answer is:
mug
'drink perhaps' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'stick around' is the wordplay.
'stick' becomes 'gum' (gum can mean to glue or stick).
'around' is a reversal indicator.
'gum' written backwards gives 'MUG'.
'for a' is the link.
Can you help me to learn more?
(Other definitions for mug that I've seen before include "Tankard" , "simpleton" , "A person easily deceived, by gum" , "Idiot" , "attack" .)
