look up any word, like darude - sandstorm:
 
1.
When you instantly regret saying something as soon as the words leave your mouth. Usually something that sounds unintentionally dirty, or just something you wish you hadn't said aloud. The tone in your voice changes halfway through the sentence as soon as you realize what you're saying. You wish you could just suck the words back into your mouth - like a vacuum.
Leafs announcer (after a hit) - "And that was two big bodies banging!"
You at home - "Woah, that was a word vacuum."
