Sat 43: linguam canīnam comēdī

[cinefactus]

Dē rē tamen ego vērum dīcam, quī linguam canīnam comēdī

I am presuming this means I have a cutting tongue, but not quite sure about the grammar. Is this some kind of idiomatic phrase?

Is it this?

Interesting thought L&S lists it in this meaning, but why would it make you speak the truth?

Hmm. Not sure. Though I did find:

"The smell of the plant resembles dogs' urine so travellers would put some in their shoes to ward off dogs as they walked along."

But wouldn't that make you a target for dogs to piss on? lol
