This is the wrong way to spell "existence". There is no "a" in existence -- or in definitely, for that matter.
The same people who spell this wrong also can't seem to grasp the difference between "your" and "you're" or "their" and "they're", something
the rest of us mastered in
third grade.
"Your definately the most excellant guitarest in existance."
--a complete idiot
Maybe if you weren't functionally
illiterate, you'd have a more "excellant" job.
