Ok, this is the best word in the english language. Just say it and it gets plastered into the back of your brain and you're hooked on this one word. Saying it over, and over, and over, and over. I love it.
A word created and abused by two people to describe things that are certain. (Most commonly spoken with a Brittish accent) Sometimes accompanied with "indeed".
That baseball must have been hit a quarter mile....
Indubitably....
Indeed....
