X Æ A-12

The secret passcode of the human vs. AI war of 3096, which will decide the fate of humanity and its many intergalactic colonies—to be ruled by man or machine. Only one human has ever been known to possess knowledge of this code—the flesh child of Elon Musk and The Star Queen (long shall she reign), Grimes.

Human 3096: "Elon, our lord, and savior has delivered to us a gift—X Æ A-12—with this we will certainly be victorious!

X-Raided

Perhaps the most controversial rapper of our time. He is notorious for the 1991 murder of Patricia Harris, a grandmother. X-Raided received a 31 years to life sentence for this, and the following year his debut album "Psycho Active" was released while he was incarcerated, a landmark in the gangsta rap genre. Paralleled by none, his lyrical content often deals with murder, rape, and an embrace of psychotic criminal activity.

X-Raided's B*tch Killa: It's halloween and I got a treat, I'm dressed like a devil and I'm handin out human meat. And every hoe that rings my bell, I'll drag em in the house and take em on a trip through hell.

x country

Often associated with great pain, this incredible sport involves running over long distances, usually not on paved roads. The average x country runner has a love-hate relationship with the sport, as it is difficult yet rewarding.

X country is all other sports' punishment.

X-plane

A flight simulator better than Infinite Flight.

I'm going to play X-plane 11 later, provided my evil teacher does not give me a crap ton of homework.

x chromosome

Chromosome which is found in both males and females. XY = male. XX = female. Sperm can be either an X or Y chromosome. During fertilization, if the Y chromosome sperm reaches the egg, then the baby is a boy. If the X chromosome sperm reaches the egg, then the baby is a girl.

Think of it as females having two copies of the same CD music album in every cell in their body, while males have one copy of that album in every cell in their body(x chromosome) and an extra single CD (the y chromosome) also in every cell in their body.

Even if the y chromosome was suffering from genetic degredation(which it is not) the effect could easily be reversed by genetic engineering.
