When six or more people surrounding a tweaker girl (aka 'bag bitch') perform various sex acts, ending after they fuck each other in the ass, and then cum at the same time on her. This is also performed while they all watch Dog the Bounty Hunter on television.
My buddies and I gave Dog's mother an awesome circle ploughing last night!

I have to admit, I enjoyed circle ploughing your children the other day.
