Rota circle
When in a group of 10 or more, having at least 2 smoking devices, and passing the bowl to your left, allowing everyone to try each piece. With enough bud, these gatherings can allow for 1 - 3 hours of continuos toking. Usually, everyone throws down the same amount, no freebies.
I was at this 25 person rota circle last night! The chick next to me was blown, & we made out in between turns! I'm still feeling the buzz!
