A'ight Blah
When you're so sick of someone's stupid mouth you just say 'a'ight... blah' like you're done with them for good.
'He just told me his favorite food is glitter.' 'A'ight... blah.'
'She's talking about her plants like they're celebrities.' 'A'ight... blah.'
'He's explaining why the moon is made of cheese.' 'A'ight... blah.'
