Excitebike

One of the 28 original release NES games that involved a motocross biker in a red suit and bike that rode in timed laps over various obstacles.

Excitebike is one of the best games ever!

Excitebike

When you are WAY more than just excited that an 80s NES game is the only way to express how excited you are.

Chill Person: "I'm pretty excited for the party."
No-Chill Person: "Eff that, I'm full on EXCITEBIKE!"

Excitebiking 

While having sex with a girl from behind (doggystyle, with both hands on her ass cheeks) you use your right thumb to apply light pressure to her asshole (the "B" button) therefore initiating turbo mode. The pace of copulation will noticeably increase along with a pleasant turbo moaning sound.

Be careful though, too much and she will overheat with uncomfort and get bitchy. You will then be sidelined for a while while she tells you to "stop fingering my asshole". Fucking may resume, however you may have already lost the race.

Use sparingly for that extra boost of speed, preferably while coming inside of her.

We could tell when Rod was Excitebiking his girlfriend because the banging got louder, the pitch of moans changed, and eventually we would hear him giggling as she yelled at him.

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.
