311 

As a former Klansman, I can confirm that the definition of 311 below is indeed correct!

The eleventh letter of the alphabet is the letter "K"; thus 3 times 11 equals "KKK," or Ku Klux Klan. 311 is sometimes used as a greeting to demonstrate membership in the KKK or simply sympathy with the Klan and its ideology.

There is also a popular rock band with the name "311" which is not at all hate-oriented, completely different meaning.

This is not bullshit, 311 is also used by KKK members!

Great band too, not in any way affiliated with the Ku Klux Klan or any other racist groups.
