lunchbox:
a person who is acting stupid, dumb, crazy, hilarious, angry, high, absent minded, drunk, retarded or weird, and can be any combination of the previous. This word originated in DC and Maryland (and other select places on the east coast), and is quite rare to be heard anywhere else. It is also hard for people to understand it's context who aren't from the area
examples:
"your a lunchbox"
"that kid is a lunchbox"
Q: "yo, remember at lunch when that retarded kid started yelling and jumping up and down??"
A:"yea what a lunchbox!"
