make you garble vinegar

gar·gle [gahr-guhl] verb, gar·gled, gar·gling, noun
verb (used without object)
1.
to wash or rinse the throat or mouth with a liquid held in the throat and kept in motion by a stream of air from the lungs.

Gargle is something I so when I have a sore throat, just before getting a cold.
You take some warm water, dissolve a lot of salt in it, and put it in your mouth. Do not swallow. Take a deep breath.
Look at the sky and breathe out through your mouth. You will hear a sound as the air goes through the salt water in your throat. Gargle is onomatopoetic - the word gargle sounds

thanks both of you.
But still don't understand.
He means blood gargle?

Hi

I can't take much pleasure in explaining this. Although vinegar is taken with food, it is a weak acid. It can hurt very badly if it gets into an open wound

If you were forced to gargle vinegar after having your teeth pulled out, it would be very painful

The quote is a threat of violence, I'm afraid
