Basically an up-market version of Beyonce. Jessonce is so important you've probably never even heard of one. And when I say one, I mean one, there is only one Jessonce. Also the originator of such words as "wid", "widda", "wiccyman" & "widdagirl". What Jessonce lacks in common sense is made up for in extreme amounts of swag.
Beyonce: "Omg, who is that!"
Person 1: "That's Jessonce! Don't tell me you've never heard of her!?!"
Beyonce: "... Of course I have. I'm so jealous of that bitch!"
Person 1; "Aw widdagirl, bless you"
