Stupidly lie about and stupidly get caught (6)
I believe the answer is:
nailed
'caught' is the definition.
(I've seen this before)
'stupidly lie about and stupidly' is the wordplay.
'stupidly' is an anagram indicator.
'about' means one lot of letters goes inside another.
'stupidly' is an anagram indicator.
'lie' anagrammed gives 'ile'.
'and' anagrammed gives 'nad'.
'ile' placed within 'nad' is 'NAILED'.
'get' is the link.
(Other definitions for nailed that I've seen before include "Fixed with metal spikes" , "Accomplished" , "Firmly fixed" , "Playful teasing remarks" , "Properly fixed" .)
