Get the Trojan Horse mug.
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.

When someone does something to make you think one thing when in fact they are going to do the exact opposite.
Tennessee quarterback Jonathan Crompton played terrible this year against UCLA so Florida (their next opponent) would gameplan against the run when actually Crompton was so good and was going to Trojan Horse them and kill them.

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.

A higher form of betrayal or backstabbing usually done to those in a "Relationship." The person that has been betrayed is completely devastated and destroyed. Similar to what happened to Troy back in the day. The victim is sent into a whirlwind of depression as they are cascaded with ball bearings of sadness lasting from a few months to a few years; their life distorted. This is the worst form of betrayal.
Cheating
Lying - In a relationship (extreme circumstances)
More specifically lying about caring and loving an individual and leading them on when they have no feelings for them what so ever.
