2B
Standard writing pencil
2B is shorthand for "to be," used in texting and informal writing: 2B or not 2B.
In baseball, 2B is the standard abbreviation for second base or a double—a hit that gets the batter to second base.
On pencils, 2B indicates a soft, dark graphite grade, two steps softer than HB.
