Comic character pulled up shorts, covering skin (9)
I believe the answer is:
spiderman
'comic character' is the definition.
(comic book superhero)
'pulled up shorts covering skin' is the wordplay.
'pulled up' shows that the letters should be reversed in order.
'shorts' becomes 'nips' (both can mean a small amount of alcohol).
'covering' is an insertion indicator.
'skin' becomes 'derma' (scientific name for the skin).
'nips' reversed gives 'spin'.
'spin' enclosing 'derma' is 'SPIDERMAN'.
(Other definitions for spiderman that I've seen before include "building worker" , "suited vigilante" , "Cartoon and film hero, kind of male arachnid" , "Cartoon-cinema hero of arachnid origin" , "Film/comic book hero" .)
