A person who's a fan of the New York Yankees, Los Angeles Lakers and Dallas Cowboys. Only watches their teams when they're in the playoffs. When their team wins, they're obnoxious. When their team loses, they don't care. So, smack talking with them is never fun. They can never hold up an argument about sports. Most of the time, they don't even know any of their team's players except for their best player.

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.

An individual that goes WAY beyond simply being a fan. This individual would rather dress up in their team colors, ignore the hot babe they are with and yell at the tv about the stupidity of the refs/coaches/players every call. They feel each play should have resulted in a touchdown and honestly can't believe it didn't. These individuals are often found sitting next to you at the bar and force you to root against their team, even if it is your team also.
