In NorCal (aside from being a word for weed), greens is used to describe the first hit of any newly packed weed. Greens are always given to the person who the weed belongs to by default, unless someone else did something to deserve them

"How was work Nate?"
"Shitty I got fired today"
"Damn that sucks bro. I'll give you greens on the next bowl"

"Aye you get greens since we're in your car"
