Premature Acceleration 

When a automobile begins to accelerate before it is prudent. Most often witnessed at intersections that are controlled by traffic lights when a driver incorrectly assumes that it is his turn to go next.

Driver: Look at that guy raring to go. I'll bet he doesn't know that it's my turn to go next.

<Car in question moves about a foot and then stops abruptly as he realizes his light did not change green>

Passenger: How embarrassing; a classic case of premature acceleration.

The act of accidentally hitting the send button on a phone text before you finished typing the entire message.

Premature Homesickness 

Being homesick before you actually leave home. May include a stomach ache, curling up in a ball, crying, lack of sex drive, over dramatic music being listened to, as well as other homesick behaviors.

Susie was suffering some major premature homesickness so I decided to just curl up with her for the night rather than push for us to have sex.

Premature Ejobulation 

Telling several people that you got a job after being informally told you got the job by someone that does not have the complete authority for you to be able to formally say you got the job.

When you speak with a company or firm representative in a formal setting, that person says you have the job, but you have to go through HR first, you tell your colleagues you have the job, you call HR and ask them to expedite the hiring process since you've already been informally offered the job and then wait several weeks to find out you are no longer being considered for the job, you have fallen victim to a spell of Premature Ejobulation.
