「一個唔該」

(pos:副詞)
<explanation>
yue:冇任何真誠嘅感激之心，引申為冇禮貌、冇規矩、覺得係應份
eng:without genuine gratefulness or concern; impolitely; self-deservingly; literally: only one "excuse me / thank you"
<eg>
yue:條粉皮一個唔該搶晒我哋功勞，喺上頭面前扮到一個人貢獻咗好多咁，好狗囉。 (tiu4 fan2 pei4 jat1 go3 m4 goi1 coeng2 saai3 ngo5 dei6 gung1 lou4, hai2 soeng6 tau4 min6 cin4 baan6 dou3 jat1 go3 jan2 gung3 hin3 zo2 hou2 do1 gam2, hou2 gau2 lo1.)
eng:That bastard took all the credit without so much as saying "thank you", and he pretends to be a major contributor in front of the bosses. That's so low of him.
