The metric unit of female beauty, abbreviated bl.
Supersedes the imperial helen
Expressed on a decimal scale from 0.00 (utterly repulsive and cock-crinkling) to 1.00 (the Platonic ideal of female beauty).
After the Italian word for beautiful
"Wow, Bella, you are so amazingly hot. I'd have to rate you at .98 bl"
"How come I don't score 1.00 bl when the damn system is named after me?"
"Because you've just woken up, there's mascara in your ear, your hair looks like a practical joke and there's a pillowcase stuck to your chin. Still adorable
"Fair enough. Now run me a bath of ass's milk and fetch costly breakfast items."
