Stupid dopes just sat (5)
I believe the answer is:
posed
'sat' is the definition.
('pose' can be a synonym of 'sit')
'stupid dopes' is the wordplay.
'stupid' indicates an anagram (in a stupid order).
'dopes' anagrammed gives 'POSED'.
'just' acts as a link.
(Other definitions for posed that I've seen before include "Took a stance" , "Positioned" , "Arranged for pictorial purposes" , "Presented (a question)" , "Modelled" .)
