Attaining a position with noteworthy speed.

Originates from Billboard Magazine's practice of putting a bullet sign in front of chart entries that have moved from one position to another with notable speed.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

A figure of speech that is associated to a number in a list. Using this figure of speech indicates that the subject either ascended the list rapidly or is overwhelmingly dominant.

Despite the beliefs of asshat children that don't understand that slang existed prior to 2003, this phrase was not made popular by any specific song, let along a song by 'Fall Out Boy'.

This figure of speech achieved widespread usage in 2001 when the movie 'High Fidelity' was released. The movie was based upon a 1995 novel by Nick Hornby of the same title. Even prior to the release of the movie, many people used this phrase, but it was not widely understood by the general population.

The phrase "Number One With A Bullet" is the title of a 1987 movie and a 1990 episode of '21 Jump Street'.

Billboard Music Charts places a bullet next to any song or album that has gotten a higher rating since the last chart came out. Regardless of how long it took the song/album to achieve this rating, if its number has gone up, it gets a bullet.

Good, and quickly becoming more popular.

Taken from the Billboard music charts, where a song with a bullet next to it means it is on its way up the charts.

It makes sense that "with a bullet" originated from Billboard Magazine, BUT, references as to it's date of origin are grossly misstated. The late radio personality, broadcast worldwide via syndicated networks, Kasey Kasem, was using the phrase on his show in the 1960's.

Another slang term for saying, "number one," as in when you are outlining a list of reasons of some sort.

Popularized by the single, "Sugar, We're Goin' Down," by Fall Out Boy (which is not their best song on the cd).

Don't be surprised if this doesn't catch on.
