After being together with the same people, you begin to figure them out and hey, out of the blue come out some nicknames. Here are some, with an explanation on a few if they are inside jokes.

Krysta Atwood- "Big Country"-I have no idea where this came from.
Sam Evans and Sarah Trevino- "Free Willy" and "Shamu"- Supposedly, when they slide, they look like beached whales. O_o
Stephanie Gibson- "Scooter"- a nickname from her Dad turned into a nickname from everybody.
Heather Kicklighter- "Baby K"- With a last name like Kicklighter, who needs a nickname? ^_^ But Daisy gave her this one day and it was just so cute it stuck, but only Daisy can call her that. :D
Vickie Kreeger- "Vickster"
Amber Morris- "Squirt"- She's so little!
Daisy Pena- "Puerto Rico"- She's Puerto Rican, and damn proud of it, too. And I call her Miss Daisy. ^_^
Ashley Shupp- "Shupp"- I find it very difficult to call her Ashley. Shupp just... fits. *shrugs*
Jessica Wolf- "Wolf"

Alex Austin- "Big Al"- She's tall, and.. tall.
Audrey Boriak and Laura Day- "Venus" and "Serena"- They always hang out together, and sorta look alike, so they got named after the famous tennis twins.
Lacy Howard- "Big Lace"and "Lumberjack"- She does look like a lumberjack when she hits that ball... BAM! *cheers*
Tara Marsh- "T"
Katy Monaghan- "Special K"- A little play on her name.
Ami Parker- "Reptar"- When she runs, her arms go forward and remind people of a dinosaur. ^_^
Kristen Gilbert- "Gilby"
Kim Nguyen- "Gim Win Win Win"- Came from one day when Katy accidentally said her name wrong, then add a play on her last name, and we've got something! The cheer "Let's go Gim Win Win Win!" is hilarious to listen to. :D
