When someone must travel between multiple houses and locations on a mission to aquire illegal drugs, usually cannabis.
A common example is for a couple people to leave one house, pick up some people and smoke some bowls at another house. Then a couple people going to the dealers house to grab say an ounce of weed, then selling some weed at another friends house. Often smoking weed the whole time.
