Its a Boston term that means when you get rowdy, fired up, and waisted, and your coming home from a bar.
After watching the sox play at the bars in Fenway, Maahk and Tim got wicked baazo and got 10 more drinks and started fighting a group of Yankee fans. They would often start fights coming home from bars; getting themselves wicked baazo and usually wicked beaten up.
When you put your hands in the shape of C's and hole them up and your representin Cape Cod Gankstas and prepstas everywhere. And some times used by shitheads from cambridge in boston
I got my C's up in the club and all the bitches knew I was a New england ganksta. Hahd core
