I was reading a novel when I came across this phrase.
"My tongue doubles back in my throat as the senses comes back to mind and I choke on the words, "I love you too."
What does the "my tongue doubles back" mean? Thanks in advance for the answer.
Double back — TFD
to go back in the opposite direction (esp in the phrase double back on one's tracks)
So you are reluctantly replying to "I love you".
