grime shit is a tweak out game on first-time smokers. It's objective is to replace many of the words you say in normal sentences with grime shit. With grime shit as the central theme. Change the subject a lot to keep them on their toes. They will most likely tweak out like hell and get either really laughy or paranoid.
