The skinny (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
dope
'the skinny' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dope that I've seen before include "Illegal drugs; fool" , "Drug - information" , "Informally, drug or silly person" , "Silly type" , "Silly ass takes drugs" .)
