Everyone's got different rules but we play:
-givebacks when you get 2 in in a row
-only chicks blow
-quasi-enforced elbow rule
Actually at the tourny there was no elbow rule of any sort... most people had almost their entire torso on the table. Pretty much bullshit considering my friend and i play pretty strict. The dudes that beat us were probably the biggest leaning fuckers in the place.
