Excite Bike 

A consistent, reoccurring "hook-up" with a less than desirable or tolerable member of the opposite sex. Some one that seems like a good idea to have over at 2 am, but you end up regretting when they are still there at 8 am.

Damn Steve, you need to stop having Jill over, she is an excite bike, and as such sucks when she is not naked and having sex with you.

Ride the bike

When a woman sits on your face with her vagina directly over your mouth (the females clitoris is at the tip of your nose) and you let her ride your face until she orgasms.

Scraper Bike 

A new trend that is a part of the San Francisco Bay Area Hyphy Movement in which people ride their tricked out bikes and go stupid, dumb, retarded while on their bikes. Generally, the bikes have nice designs, such as duo-tone paint jobs, and rims or spinners. The term was coined by the rap group Trunk Boiz of Oakland, California.

Jerome: Me and my buds was on our scraper bikes picking up on girls. My scraper bike go hard, I don't need no car.
Tyrone: That go!
Jerome: We was ghost riding them too.
Tyrone: That sounds like hella fun, bud.

denim bike rack

when seeing a woman in really tight jeans from the front (or very rarely seen on the rear) and being able to fit your bike tire in the gap and use it as a denim bike rack.

Look how big the gap in "Suzie"s jeans are. We can use it as a denim bike rack while we go in the store.
