A virus-like program that pretends to be something else in order to get into the system.

From _The Iliad_, by famous dead poet Homer, when the Ithacans gained victory by hiding in a huge wood horse so they could get into Troy.
The Trojans were not in the gifted program at warfare school.

Jul 15 Word of the Day
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.
Billionaires are having a dick swinging space race while the earth experiences record breaking heatwaves that cause sea creatures to literally cook inside their shells. We need planetary quarantine.

A play that is run when a boy and girl want to have some privacy at either one of their houses, but they need to keep it a secret from friends and neighbors. They run the play by meeting up at a remote location, where one of them climbs into the backseat of the other's car and lays down, so they drive together into the garage of the home with no one seeing. The garage door is then closed behind them, and they are free to enjoy each other for several hours, uninterrupted.
Girl: I'm home alone, and I need to see you. So, so, bad. But everyone will see if you cum over here right now.
Boy: Ya. Um... Not if we run the Trojan Horse. Let's set it up. I'll meet you a few blocks from your house in 30 minutes.
Girl: Yes! Perfect!
Boy: YOU are.
