How it's used
This term carries a strong sense of moral condemnation, implying that the act of reporting is motivated by malice or a desire to sabotage someone rather than a sense of justice. It is frequently used in office or school environments to describe someone who curries favor with superiors by reporting their peers' minor infractions. The imagery suggests a hidden, cowardly act of pointing a finger behind someone's back.
Examples
He always snitches, so nobody dares to tell him secrets.

Common mistake
Do not use this term in formal or professional settings, as it is highly derogatory and implies that the person being reported is a victim of unfair betrayal. It is strictly a colloquial term for informal social contexts.
