Past-tense of the word lunch. See that
definition for a good idea of what lunched is. It means to do something stupid, or to mess something up. It originated from the
stoner-culture, and used to be associated with being
high or burnt. But that is not always the case anymore. Go read the definition for lunch if you still don'
t understand.
You also hear, "lunched out". Same thing, just a different way to say it.
Definitely regional, I've only heard the word used in DC when I lived there, and we said it ALL the time! Since moving from there, no one I've met has ever heard of it.
Awww,
man, I lunched! I drove all the way here and forgot the dang receipt!
After all that planning, he lunched out and walked through the security gate with a
nug stuck to his fleece! Needless to say, he
got arrested, what an idiot!
