'scoffs at' is the definition.
(I've seen this in another clue)

'fat-headed boors' is the wordplay.
'fat-headed' becomes 'f' (this could be a standard abbreviation I've not previously seen).
'boors' becomes 'louts' (I've seen this in another clue).
'f'+'louts'='FLOUTS'

Can you help me to learn more?

(Other definitions for flouts that I've seen before include "Disobeys openly and scornfully, as with law (6)" , "Of lust (anag.)" .)

I've seen this clue in The Irish Independent and The Irish News.
