a secret organization only known by those who have a calculator of the same name. While other math students fumble with equations, the TI-89er relaxes as s/he's just used the solve() function. And as all the other dumbasses observe, s/he simple responds "TI-89," and other students will simply cower and look elsewhere.

Graphing calculator that has the meaning of life. Not only does it do math for you, but it also does your laundry!
The AP board is examining your test, and sees that you miraculously have the answer in one step. The justification is "Ti-89".....automatic 5!

1. A far superior model to its counterpart, the ti-83. Can graph 3D functions, differentiate and integrate and calculate Taylor series. The symbol of a true math or science geek.
2. The main reason I'm passing college math.

"Oh man you're so lucky, I still have only an 83, but I got Pimp Quest, mother f-er."

Get the ti-89 mug.
God's calculator. Most of the questions of the SATs that require solving for variables or solving trigonometric identities can be solved by simply plugging them in to this beast of calculator.
John: "Hey Randall, what did you get on the math section of the SATs?"
Randall: "Oh, just an 800"
John: "800?!?! Didn't you get a 550 last time?"
Randall: "That was before I got my TI-89 Titanium!"
