What is a juggler?

One person in my facebook sphere called herself a juggler. Now what exactly is a juggler? I looked the word up and found this:

jug·gler - ˈdʒʌglər'/ [juhg-ler] –noun

1. a person who performs juggling feats, as with balls or knives.
2. a person who deceives by trickery; trickster; one that uses tricks, deception, or fraud.

So for simplicity sake, just know that when a person says he or she is a juggler, it can mean more than just one who perform juggling feats.
