What do the fours dots in a northern hispanic gang represent?

Question

how are they earned

Answer 1

Let me break it down for you.

The Northern Hispanics you are referring to are Nortenos, which means Northerner in Spanish.  They are a large scale gang with thousands of foot soldiers spread out all across Northern California.  

N is the 14th letter of the alphabet, so Nortenos use the number 14, and all it's variants (14, 1-4, XIV, ::) to signify their gang affiliation.  The four dots do not represent any specific thing, such as murder, theft, drug running ect., but are just another gang tattoo.

Don't mind the chick below me, she's a scrap.
