A nickname for someone with the birth name Nelli. Only awesome Nelli's can go under the term Nellz (or any variation of your name with a 'z' in it for coolness). It should be noted that non-awesome's going under Nellz might experience heart failure, as the burden is so great.

Basically the coolest person you would ever hope to meet, ever. Usually you experience an epiphany after meeting Nellz.

Also, she is a gangstuh.
Nellz, you are so cool. I can't believe you can handle that z in your name!

This gives an excellent example of O'Nellas straw by showing how a crazy straw with all its twists and turns will take longer to bring the liquid past your lips and down your Flesh pipe.

Nellieland

The most perfect place in all the world, ruled by Jody, a.k.a. The Jodster. It is a tiny slice of heaven on lake Ossipee. There, girls sing and dance... sometimes in their underpants! The people there are amazing and every day is too much fun. Chocolate Chip pudding is sacred. Huckins camp - for two weeks or four - how I wish there were more.
Oh gee golly, I wish I was in Nellieland right now!

Hey insert a Huckins Friend only 5 months, 17 days, 2 hours, 10 minutes, and 35 seconds until camp begins!!! YAYYY HUCKINS HEARTS 143
