The male notion of 'look'. An amalgam of 'bloke' and 'look': a half hearted glance or impatient scan of a general area whilst searching for an object but without specific focus or proper attention. A man will 'blook' for something, swear it isn't there and a woman will look in the same place and it will have been there all along. Related in root to 'blisten', the male version of listen.
'Sandra where's my hacksaw? I left it in the shed and it's gone'
'Did you look properly or did you blook?'
'I looked properly I'm not stu....oh it's here.'
