binary rating system

Instead of ruthlessly judging members of the opposite sex and using a tedious 1-10 (or 0-10) you boil it down to what really matters: whether or not you wanna bang. So you'd rate someone with whom you would like to have sex a one And someone with whom you would not have sex a zero.

Tony said she's a 7, but in the binary rating system, all that matters is that she's a one.
