In the drinking game of beer die, biz is when the dye is thrown and stops rolling with five showing on the top. You are not allowed to say the actual word five to describe how the die landed tho, so you must say biz. then you make the other team take a sip of their beer
die thrower- "Hey man what did it land on?"
opposing team member says reluctantly- sigh, "Biz"
die thrower- "hah drink up bitch"
