Thinking something and then saying it with out more thought or consideration to its effect; saying what's on your mind out loud without thinking about it.
Your boss is talking to you about your performance and without thinking about it you mindvomit telling him he's a complete dick, and he can shove his job right where it fits.

A friend tells you about their day and you mindvomit, telling them you don't care nor have you ever cared about their endless shitful life.
