A'ight Blah
When someone's words are so dumb you just shut them down with 'a'ight... blah' and pretend you never heard them.
'He just said his job is to count clouds.' 'A'ight... blah.'
'She told me her dog can do algebra.' 'A'ight... blah.'
'He's explaining why the sun is a disco ball.' 'A'ight... blah.'
