Poor-quality (3)
I believe this is a double definition.
'poor' is the first definition.
(similar in meaning)
'quality' is the second definition.
(I know that bad is a type of quality)
(Other definitions for bad that I've seen before include "Evil, below standard or off" , "Severe; of low standard" , "Mouldy, off" , "Spoiled or evil" , "Rotten, evil" .)
(Other definitions for third-rate that I've seen before include "Very inderior in quality - do a count" , "Very inferior in quality, using ordinal number" , "Of very poor quality" , "Very inferior in numerical way" , "Very inferior in quality in numeric description" .)
