What does blurted out mean?

"Blurted out" means to say something suddenly and without thinking carefully, often because you are surprised, excited, or nervous.

Here are some examples:

* "When the teacher asked who had done it, John blurted out, 'It was me!'"

* "She was so excited about the news that she blurted it out before she could even think."

* "He was nervous during the interview and blurted out the first thing that came to mind."

Essentially, it suggests that the words were spoken impulsively and with little to no planning or consideration.
