a immature high school boy act in which an innocent student has their backpacked emptied, flipped inside out and has their belongings placed back into the backpack zipped up like a lunchbox. People are often seen walking out of the classroom holding their lunchboxed backpack because there is no way to hold it.

1. A robust individual who tends to replace all other condiments with mayonaisse. Sometimes the mayonaisse becomes the entire meal for a true lunchbox.
2. Someone at lunch, who once finished eating, stares at your remaining food until you offer it to him.

Someone whose brain is like a metal box with an apple core, a Flinstones vitamin (Barney), and a couple potato chips clanging around in it. And that's all.
Megan probably won't remember she's supposed to meet us here even though I reminded her her four times. What a lunchbox.

When you or your co-workers eat lunch in the same room and stink-up the place with your smelly food.
It's 12:30 and the I.T. department door is closed. They must be lunchboxing their office again because I can smell that food from down the hall.

1) A box to keep food, especially a lunch. Often found at schools, picnics and such.
2) Someone fat who looooves to eat, such as Silent Bob from such films as "Jay and Silent Bob strike back"
