「炒蝦拆蟹」

(pos:動詞)(sim:屌蝦拆蟹)
<explanation>
yue:講粗口；#爆粗（因為報紙會用魚蝦蟹嘅符號代替粗口，所以用咗魚蝦蟹去借代粗口）
eng:to use bad language; to swear; literally: to stir-fry prawn and dress crab, since signs of fish, prawn and crab were used to replace swear words in newspaper
<eg>
yue:條友成日喺度炒蝦拆蟹，冇嚟斯文。 (tiu4 jau2 seng4 jat6 hai2 dou6 caau2 haa1 caak3 haai5, mou5 lai4 si1 man4.)
eng:That guy is always swearing and doesn't look classy at all.
