Tape over head (4)
I believe the answer is:
pate
'head' is the definition.
(humorous term for the head)
'tape over' is the wordplay.
'over' indicates anagramming the letters.
'tape' anagrammed gives 'PATE'.
(Other definitions for pate that I've seen before include "Posh 8" , "loaf" , "Meat paste, perhaps de foie gras" , "Savoury paste; head" , "Tape for a head" .)
