Lunchpin 

The central person in a group of friends or co-workers whom decisions for going out to eat revolve around, and without whom no decision can be reached.

Paul is the lunchpin of our team -- if he doesn't choose what restaurant we're going to, we won't go anywhere.

Unsure if this is regional. My crew in DC used this nonstop, but never heard in in the places I've lived since: Chicago and New York.

Please send me an email if you've heard it elsewhere.

Yo, your boy Juarez was lunchin' last night. He smoked a whole blunt of ill and tried to jump out the window of Shaniqua's window (she's on the 15th floow). But he was so fucked up he couldn't even figure out how to unlock the window. Damn.

Lunching 

This word was very popular in and around the Washington DC area. I first heard the word circa 1985 in high school. Veriable definition. Could be crazy, high, insane, tripping, pissed or thousands of other meaning. Definition is dependent upon the context. Example

"My friends mom sold me some bomb weed and then tried to get with me?! THAT CHICK IS LUNCHING!"

lunchin

A word derived from the stoner-culture. It means to act stupid, or do something stupid. It also can mean to be burnt, meaning you are slow or blank, because you're zoned or high.

It is DEFINITELY regional! Me and my crew from DC used it religiously. Once I moved to Miami (and now other parts of Florida) people had NO CLUE what the word was. No one from down here has ever heard of it!

See also: lunch out (verb or noun), lunch box (noun), lunch/lunched (verb)

They said they called me and I missed my turn, but I never left the room! I must have been lunchin or something.

Can someone go get him, we're 15 minutes late already and he's still in his room lunchin!

I can't get through to her at all, man, she's totally lunchin out over it.

He got arrested last night, the kid drove right into the back of a parked police car, now THAT is lunchin!!
