18-00

18-00, eighteen-zero-zero, adj., D&D-ism 1. in Advanced Dungeons and Dragons, 2nd. Ed., the highest possible Strength stat for a mortal player character. 2. describing the best possible. 
Ex: She's not too bright, but she's 18-00 in the looks department. [GJ1]
----
Addendum: In the original Dungeons and Dragons, 18 was the highest possible score for any stat, unless the character was a demigod. To placate players who wanted their Arnold Schwarzenegger-wannabe characters to have higher-than-18 Strength stats, 2nd. ed. added a 1-100 bonus system, to describe gradations of superstrength between 18 (human maximum) and 19 (demigod). So, for instance, a character might have 18-35 Strength, which wasn't as good as 18-50 Strength. The new maximum was 18-00. [GJ1]
