90 

An interstate and one of the longest roads in the U.S. from Boston to Seattle. Nothing for thousands of miles from Western New York State to Central Montana.

90 is very dull to drive if you can stand to 3 or 4 day drive.

90's kid 

1. Someone whose childhood was significantly influenced by the 1990's.

2. What has become a meaningless term for anyone who remembers their childhood, thanks to overuse by prematurely nostalgic teenagers and young adults.

1. Billy is a prime 90's kid, being born in 1987. His first memories started in 1990 and he became a teenager in 2000.
2. Person 1: "Only 90's kids will remember playgrounds, rock paper scissors, Samurai Jack and hide and seek."
Person 2: "Dude, playgrounds, rock paper scissors and hide and seek still exist. And Samurai Jack isn't even from the 90's."

90's Nickelodeon 

The time when Nickelodeon was worth watching. It featured shows such as Are You Afraid of the Dark?, My Brother and Me, Alex Mack, Ren and Stimpy, Doug, Salute Your Shorts, etc. Now Nickelodeon has sold out and if they brought back the old shows, their network would be doing better.

90's Nickelodeon rocks my socks off!

90 to nothing 

The term is slang, used heavily in the South. It means you have a millon things to do and you are moving fast to get those things finished.

"This cute, little, blonde, girl I know, way down South, talk's 90 to nothing, drives 90 to nothing, and is 90 to nothing at everything...and I mean everything...unless she's asleep, then I imagine she dreams 90 to nothing!"
