put one's foot in one's mouth

Speak then regret

To put one's foot in one's mouth is to say something embarrassing, tactless, or inappropriate—often revealing information better left unsaid or making an awkward situation worse.

The image is of literally stuffing your foot into your mouth, rendering you unable to speak sensibly.

I really put my foot in my mouth when I asked about her husband—they'd just divorced.
