Someone who used to work and can still work and has skills but chooses to draw unemployment and mooch off friends and family. The lunchbox typically is up on all the latest TV shows and often can discuss the characters on various soap operas with women while you are buying them drinks at the bar. Lunchbox gets laid, but goes ugly early because he is only a shell of the man he used to be.

He's called Lunchbox the same reason you call fat guys "Tiny" and bald guys "Curly." Lunchbox has no reason to put a meal into a container for transportation purposes or to be eaten later. Lunchbox has been konwn to subsist on jam sandwhiches- two pieces of bread pressed, or "jammed" together, for weeks at a time. Additionally, the Lunchbox tends to become nocturnal and uses the phrase "crack of noon" frequently.
Glen, have you heard from Lunchbox recently?

Dude, I took Tuesday off to go to the dump, stopped by his apartment and we smoked me out of weed in 20 minutes.

Get the lunchbox mug.
A group-sex act in which three males penetrate a female, with two penises in her vagina and one in her mouth. The female is also penetrated anally with a butt plug or dildo. The act ends with the three males ejaculating in the female's mouth ("lunch time"). There are subclassifications and variations, for example: "bento box" (Asian female), "A-Team lunchbox" (two penises in the anus and a dildo in the vagina), "no thermos" (butt plug or dildo not present), and "with baggies" (condoms present).
My girlfriend is into wild sex. Tonight she wants me and my buddies to lunchbox her. If she's feeling relaxed, she said said she might even try an "A-Team."
