A close-knit group of that consists of (usually) male members. A group of this
nature does
everything together, including, but not limited to, eating, singing, and doing work. A member or a K1 or similar group never lets the other members of the group down. The K1 is short for your "1st Krew", meaning your closest group of
friends, and is the first place that you go for advice.
Guy# 1: Dude, I was doing work on this
chick, but I don't know what to do
next.
His bro: yo, you should ask the K1.
