Extreme foolishness (6)

Ross

I believe the answer is:

idiocy

'extreme foolishness' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for idiocy that I've seen before include "Predatory seabird" , "Extreme foolishness" , "Imbecility" , "Foolishness, asininity" , "Stupid act" .)

I've seen this clue in The Times, the Penny Press and the Newsday.
