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.

Noun. Invincible person of great prestige. Can take damage and come out nearly unscathed. He is one bad momma-jamma and often rides pimp style in his Kuribo's Shoe. His name is dope, his chicks are fly, and you better hit the ground when his knuckles float like a butterfly and sting like a trout.

Cheese is his ambrosia. Caffeine, his nectar.

He is cognizant of those he relates with and always takes into account their views on even the most trivial matters. He never exacerbates things. He is Lunchbox. Fear the Lunchbox. Be one with the Lunchbox. Just BE the Lunchbox.

Lunchboxes often like to ride on their barstool of love, though they sometimes take the train.

They like to dance all about and put their big toe in your mouth while you scream and shout and threaten to "poke out your innards with a spatula" if you spread rabies in Church one day.

This shouldn't mean that you should fear the Lunchbox. By all means, no. You should befriend a Lunchbox today because they have nachos and everyone knows that the Nacho People will rule the world of Salsa. With their leader, Enchilada by their side, the Lunchboxes will enslave humanity.

Will you be a part of their enslaved or will you be dead? Actually, the best answer is "to be a Lunchbox" but not all are worthy of such a title.
Oh shit dude, a car fell on this guy and fell in some lava, all while his dope rapping skills saved his ass from a drive-by. He is the Lunchbox.

"Is that Lunchbox?"
"Yeah. I guess meth is another failed diet plan."

The inside of your girls bellybutton which can hold a piece of cracker or some trail mix, for a quick energy boost, whilst going down on her.
Me: “what is this in your bellybutton?”
Girl: “I packed a small snack for you!”
Me: “awe, how thoughtful, you even packed it in a tiny 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.
