Ok, lil Vatos (Can I still use Vato?)
I'm a lil bit older than most of you homies, I'm 36 now and grew up in the 408.
Ese was always used, even up to the mid to late 90's, especially in San Jo, Santa Clara, Mountain View and Sunnyvale and can't speak for the 415 or the east bay, althought I know some old homeboys from SFM and they spoke calo as well.
No one ever said "Nigga" or "Dawg", it was alway "Holmes", straight Old School style and you would never call a veterano Nigga, or Dawg, they would look at you funny or worse.
I never heard anyone call somone Ene, that just sounds weird, but hey, its the pepsi generation now and I'm retired from putting in work, I paid my dues, Home Skillet (can we use that one?)
