Interstate Bicycle 

When a girl does not take a shower and especially does not wash her vagina. She then procedes to sit on the face of the male and moves in all directions making the nose of the male ride up even farther into the crouch of the female. To simulate like riding a bicycle, when the bike seat is the males face.

"Yeah my girlfriend gave me an Interstate Bicycle last night and i almost threw up"

Guy: I am not letting you trick me into a Interstate Bicycle again. you better wash that thing again.
Girl:FINE!

Interstate 25 

A major interstate in the western United States running from Interstate 10 in Las Cruces, New Mexico to Interstate 90 in Buffalo, Wyoming. It passes through 3 states; New Mexico, Colorado, and Wyoming, as well as passes through the cities of Las Cruces, Albuquerque, Santa Fe, Pueblo, Colorado Springs, Denver, Fort Collins, Cheyenne, and Casper.

The portion of the freeway through Colorado is heavily urbanized from Pueblo to Fort Collins and is known as the "Front Range Urban Corridor," which is home to most of Colorado's 5 million people.

The entire length of Interstate 25 is rather scenic, especially the Colorado portion and parts of the roadway through northern New Mexico.

Man, I need to get to Albuquerque from Denver quickly. I know, I'll take Interstate 25, get there fast and be able to look at awesome mountains the whole way!

Interstate of mind 

Phenomena that occurs after exiting the interstate in which the driver continues to drive at high speeds (65+) through low speed zones (30-) such as neighborhoods and school crossings. Many speeding tickets are thought to be the result of this.

"Do you know how fast you were going through town?"

"75, I know....I'm still in the interstate of mind."

interstate 80 

The coolest interstate, in that it manages to link the great cities of New York, Chicago and San Francisco together. At over a couple thousand miles, it's also a long ass interstate, and manages to pass through a bunch of nothingness.

Pioneers used the Oregon Trail, we use Interstate 80.

Interstate 394 

A 3-digit spur route off I-94 in Minneapolis, Minnesota. It connects 4th St/Washington Ave/3rd St (the actual end of the freeway is uncertain to me) to I-494. It is about 10 miles long. Between State Highway 100 and Interstate 94, there is a "high occupancy vehicle" lane which in the morning rush hour is used for eastbound traffic and in the afternoon rush hour is used for westbound traffic.

This is like my favorite freeway number of all time. The interchange with I-94 sucks and needs to be reconstructed though.

Interstate mind

The state of mind one gets after driving on the highway/interstate for an extended period of time, where the driver feels like they are driving slow once on city and residential streets, and/or speed without realizing it.

After driving for hours Thomas got off the highway and had interstate mind, and found himself speeding through the neighborhood.
