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.

Nov 27 Word of the Day
A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
That fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.

Get a Trojan Horse mug for your boyfriend Vivek.
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.
