How it's used

Refers specifically to liquid food waste or kitchen slop, often associated with pig feed in older or rural contexts. It carries a strong negative connotation of being filthy, rancid, or unfit for human consumption. It is rarely used to describe general sewage or industrial wastewater, which would be referred to as 污水.

Measure word

Examples

This swill smells really bad, hurry up and pour it away.
Are you trying to feed pigs? Why did you bring back this swill?

Common phrases

to pour out swill

Common mistake

Do not use this to describe general dirty water or sewage, as it specifically implies organic food waste that has gone bad. Using it for regular dirty water sounds like you are calling it rotten food.
