A categorical system used to rank someone on your desire to engage in sex with them. Most commonly ranked between 0 (lowest) and 10 (highest) but can also be categorized by celebrities such as Roseanne (lowest) and Anna Kournikova (highest).
Look at that girl over there. On the do-able decimal system she is a Roseanne for sure.
