Instead, it's a metaphor meaning:
* You are speechless: You are so surprised, shocked, or overwhelmed that you can't find the words to speak.
* You are shy or nervous: You are hesitant to speak because you feel awkward or uncomfortable.
* You are unable to articulate your thoughts: You are having trouble expressing yourself clearly or making your point.
Here are some examples:
* "When the teacher called on me, my tongue was hung in the middle of my mouth. I didn't know what to say!"
* "He was so embarrassed by his mistake, his tongue was hung in the middle of his mouth."
* "The news was so shocking, it left me with my tongue hung in the middle of my mouth."
Essentially, it describes a state of being speechless or having difficulty speaking, often due to a strong emotional reaction.
