I am an employee, and I send an email to my colleagues about sport, so I mark it "NBR" to show it's a non business related email.

Ben: That girls NBR is nasty. Too much nipple not enough boob.. If the nipple's too small it feels like you're playing with a guys nipple and it's just not right either.
A healthy NBR is considered approximately 1 part nipple for every 6 parts boob.
