coffee table rules
When your buddy is impatient and doesn't want to "wait his turn" on the salty wench. You share your wench but strictly "no homo" style. Coffee table rule is defined as the rule of "you stay on your side of the coffee table (the coffee table being the females back as she is on all fours) and I'll stay on my side". The females back can also be USED as a table to set your beer or other beverage of choice on, assuming all parties are in sync and things don't get too wild.
