"to get boxed" is when you come home and your things have been unexpectedly boxed up and put out on the curb. Most commonly seen in relationships, however, this can happen to anyone.
"I just got home and my stuff had been thrown out on the curb!!"
When you win an argument and your opponent has no comeback or is speechless. Then you draw a square in the air signifying that you have won.
Person 1: "What? Star wars IV was definitely made in 1979"
Person 2: "No I was made in 1977"
(checks on wikipedia)
Person 2: "Ha! 1977! You just got Boxed!"
