「阿媽係女人」

(pos:語句)
<explanation>
yue:比喻為一啲好明顯、係人都知嘅嘢；攞嚟窒人講廢話
eng:'mums are women', i.e. something trivially true, something everybody knows; used to imply satirically that someone is stating the painfully obvious
<eg>
yue:鬼唔知你阿媽係女人！ (gwai2 m4 zi1 nei5 aa3 maa1 hai6 neoi5 jan2!)
eng:Oh, come on, who doesn't know that? (literally 'Ghosts don't know your mum is a woman!')
