怪阿姨怪先森
[guài ā yí guài xiān sēn]
'Weird auntie, weird mister', which humorously refers to peculiar individuals. 'Auntie' (阿姨, 'a-yi') and 'Mister' (先生, 'xian-sheng') commonly refer to older female/male figures. But here 'weird' implies out-of-ordinary characters, highlighting unique and perhaps slightly odd or unconventional traits.
