How it's used
While referring to physical waste like coffee grounds or dregs, this term is frequently used metaphorically to describe people who are considered morally corrupt or worthless. It carries a strong negative connotation, similar to calling someone human trash. In everyday speech, people often prefer the more colloquial term 渣 for physical residue, reserving 渣滓 for more formal contexts or harsh insults.

Common mistake
Learners often confuse this with 渣, which is the common, everyday word for physical dregs or crumbs. Using 渣滓 in casual conversation to describe simple food scraps can sound overly dramatic or formal, as if you are making a moral judgment rather than just talking about trash.
