Massive cuddle with European (4)
I believe the answer is:
'massive' is the definition.
(I've seen this before)
'cuddle with european' is the wordplay.
'cuddle' becomes 'hug' (I've seen this in other clues).
'with' says to put letters next to each other.
'european' becomes 'E' (abbreviation e.g. EU).
(Other definitions for huge that I've seen before include "Great in size or amount" , "Extremely large" , "Mammoth" , "giant" , "Jumbo" .)
