Element amusing me getting drunk (9)
I believe the answer is:
magnesium
'element' is the definition.
(magnesium is a kind of element)
'amusing me getting drunk' is the wordplay.
'getting drunk' indicates anagramming the letters.
'amusing'+'me'='amusingme'
'amusingme' with letters rearranged gives 'MAGNESIUM'.
(Other definitions for magnesium that I've seen before include "Silver-white metallic element" , "Silvery-white metallic element" , "Silver-white metal" , "member of a second group" , "flammable element" .)
