Re: 打壞 (sickly)

I probably heard the noun phrase 打壞後生 from the mouth of the late 關德興 when he scolded his disciples in his Wong Fei Hung series. 廣州話方言詞典 (p.29) has the following entry (which I translate into English):

打壞 da2 wai6 It is the shortened form of 打壞種 (a species messed up while breeding) and is generally used to describe the feeble or deformed state of human body.

“A Dictionary of Cantonese Slang” (p.66) also has a 打壞 entry but it is not related to the “feeble” meaning:
daa waaih 打壞 [to do bad] to misbehave; a badly behaved inmate (prison officer jargon).
