# "He's always shooting his mouth off."

/hiːz ˈɔːlweɪz ˈʃuːtɪŋ ɪz maʊθ ɒf/

English · American Slang 

B 

"He talks too much — recklessly, all the time."

A vivid mid-19th-century American metaphor casting careless speech as undisciplined gunfire — words flying outward without aim, hitting whoever happens to be standing nearby.

### Word by Word

| 1. | shoot | /ʃuːt/ | Old English *scēotan* — "to throw, project, hurl forth." The Germanic root long predates firearms; the gun-related sense came later, but the older sense of *projecting something outward* is what makes the metaphor land. |
| -- | ----- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 2. | mouth | /maʊθ/ | Old English *mūþ* — the speaking organ. Standing in here for speech itself, the way *tongue* does in "hold your tongue."                                                                                                    |
| 3. | off   | /ɒf/   | Old English *of* — "away, outward." The phrasal-verb particle does the work of release: *shoot off* means to discharge or fire, with all the force of expulsion.                                                            |

### Literal Sense

To *discharge one's mouth like a firearm* — to fire off speech the way you'd fire off a six-shooter, with the same lack of aim and the same indifference to who's standing in front of you.

> "Words are loaded pistols." — Jean-Paul Sartre 

### Origin

First recorded in the mid-19th century, almost certainly in the American West. The metaphor was no stretch there: six-shooters were everyday objects, reckless men were everywhere, and the line between firing without aim and talking without thought was already legible to anyone who'd spent an evening in a saloon. The Germanic root of *shoot* — *scēotan*, "to throw or project" — meant the leap from gun to mouth was instant; words simply became another thing you could discharge.

The phrase traveled east through the cowboy-and-saloon mythos that flooded post–Civil-War American writing, and from there into general British and American usage. By the early 20th century it was thoroughly mainstream — no longer Western regionalism but the standard English shorthand for indiscretion. Its quieter cousin, *shoot the breeze*, didn't appear until the mid-20th century, a hundred years later.

### Usage Notes

**Register**Informal, mildly disapproving. Almost never neutral — to say someone is "shooting his mouth off" is to criticize them, even if affectionately.

**Common contexts**Bragging at a bar, leaking a secret, blurting out something in a meeting that should have stayed unspoken, scolding a child or junior for indiscretion.

**Compare** *Run one's mouth* — similar, slightly more aggressive, more confrontational. *Blab* — childish, less violent imagery. *Talk out of turn* — formal, polite, schoolroom register. *Shoot the breeze* — gentler cousin, just idle chat with no harm done.
