look up any word, like blumpkin:
 
1.
Not to be confused with the breakfast club, the lunch bunch is that group of friends that you sit with at lunch and generally are your bros. These groups usually consist of:
A funny guy( or two)
Some dude to add the sex news and jokes
A guy who knows everything about everything
A guy to do stupid things
And a couple girls to keep the peace.
You will generally trust these guys with everything and rely on them completely for company
So who were you hangin out with?
o just the lunch bunch.
