When someone calls you a rat, they’re usually saying you’ve betrayed their trust or told on them. People started using “rat” as an insult because rats seem sneaky and tend to run away when there’s trouble—kind of like someone who spills secrets or betrays their group. This idea popped up in the 1800s and, for better or worse, stuck around.
Folks use “rat” to describe anyone who shares private info, and it’s almost always meant as an insult. The word packs a punch because it suggests you’re not loyal and maybe can’t be trusted. Ever wonder why tattlers get called this? The history behind it is more interesting than you’d think.
Why Are People Who Tell Called Rats?
When you call someone a rat for telling on others, you’re saying they broke trust by sharing secrets. The word has a long history, and its meaning shifts a bit depending on the situation.
You’ll notice there are differences between rats, snitches, and stool pigeons. People came up with these names because of how rats act, their reputation, and just how folks view informers in general.
Meaning and Modern Usage of ‘Rat’
Today, if you call someone a rat, you usually mean they’re an informer or a snitch. They tell on others, often to the police or a boss.
A “rat” comes off as disloyal—someone who breaks the group’s silence. You might hear the word in criminal circles or at work.
In some groups, it’s about the worst thing you can call someone. The insult covers anyone who exposes secrets, often for their own gain or to dodge trouble.
Origins of the ‘Rat’ Label for Informers
People started calling informers “rats” because they linked the animal to negative traits. Rats live near people, often in dirty places, and they spread disease.
That made rats symbols of filth and betrayal. Over the centuries, the connection just got stronger.
By the 16th century, folks used rat for people they thought were dishonest. The informer meaning showed up later, around the early 1800s, when rat meant someone who told on others to the police.

Key Differences: Rat vs. Snitch
Even though rat and snitch both mean someone who tells, there are some differences. A snitch is usually someone who talks under pressure or to save themselves.
People use it a lot in criminal circles. A rat can mean anyone who deserts their group or works against others, not just someone who informs.
The word fink is kind of like snitch, but it’s old slang now. Stool pigeon or stoolie means an informer who sets others up.
Here’s a quick table for reference:
| Term | Meaning | Common Use |
|---|---|---|
| Rat | Informer, disloyal person | Criminal, workplace |
| Snitch | Informer under pressure or self-protection | Criminal groups |
| Fink | Old slang for snitch | 1920s–1940s slang |
| Stool pigeon/stoolie | Informer who tricks others | Police informants |
Other Slang Terms for Informers
Beyond rats and snitches, there are plenty of other nicknames for informers. Canary comes from jail slang—people say informers “sing” like birds.
CI stands for confidential informant, and police use it a lot. Pigeon and stool pigeon started as words for birds used to trap others, but eventually became slang for informers.
All these words carry a heavy negative vibe. They warn you not to trust someone who gets called one.
These names show how people see informers—not just as untrustworthy, but also as tools for authorities. No matter the word, it always marks someone as willing to betray trust.
Cultural and Historical Perspectives on Rats as Traitors

This idea grew, and soon calling someone a rat meant they’d abandoned their duties or friends when things got tough.
Rats as a Symbol of Betrayal and Desertion
People often connect rats to betrayal because they see them running away from danger. Rats slip into hiding while others face the risk, so folks started thinking of them as deserters.
This image became even stronger in crime slang. In neighborhoods or prisons, calling someone a rat means they’re a traitor who reveals secrets or “snitches” on others.
The phrase “snitches get stitches” warns that rats will pay a price for betraying trust.
