A number commonly known for superstitious beliefs about it being unlucky. Originally it was a holy number, but somewhere along the way it was hijacked and portrayed as unlucky. Fear of this number is called triskaidekaphobia.

Thirteen stands for M, the thirteenth letter of the alphabet. M is for Mexican Mafia. Any real Mexican gang that lives in S. California starding from Bakersfield and down all the way to San Diego should be affiliated with 13.
