On Nicknames

I'm not sure if this is just part of my husband's world or if this really extends to all Mexicans, but I don't really know my husband's friends names. What I do know instead are their nicknames. It seems that everyone has one and some aren't flattering.
Take my husband for example. His real name is Jesus but his nickname is Chuy. How did Chuy come out of Jesus? If you ask him, he will say it's because his name is Jesus Emanuel. If he was Jesus Manuel he would be called Chema. Oh, that cleared it all up! Clear as mud, thanks honey.
There are other common nicknames that don't seem to have any relation to the real name.
Francisco becomes Kiko or Paco or Pancho
Jose becomes Pepe
Rodolfo-Pop0
Ok I guess we have a few of those as well. One might not immediately derive Bill from William or Betsy from Elizabeth if they were learning English as a second language.
But then there are the nicknames based on someones appearance. Close circles of friends might have funny nicknames for each other, but these names are not generally shared and used as the standard.
For example my husband's soccer friend is called El Negro, the black one. I don't even know El Negro's real name. This is how widespread and understood his nickname is. I'm not sure if my husband even knows his real name. When El Negro's family was here the other day, I even heard his wife call him that. Given this countries history and struggle for civil rights, I'm going to guess no one would really venture to call anyone, Hey Blackie! (Just a side note here he's not even black!)
So I've compiled a list (with the help of my husband) of some nicknames you just wouldn't hear used in the White American vernacular.
Nicknames to describe the color of your skin
El Guero- the white one, Whitie
El Negro- the Black one, Blackie
El Moreno- the Brown one, Brownie
Nicknames to describe other features
Tofeo- trompudo y feo, big ugly trumpet (mouth)
Gordita- Little Fat one, (Not to be confused with Gorda- just fat which would be considered insulting)
El Patotas- Big Foot
Cepe- cejas de perro, eyebrows of a dog
el foco de mercado- supermarket lights, because the person had a lot of zits
el bocho- Volkswagen beetle, because the person had big ears
pelon- baldy
Pope- After Popi, because someone had big arms
I've yet to find what is really embarrassing in Mexican culture. Being called El Foco and drawing attention to the fact that someone has really bad acne seems embarrassing to me. But in my experience Mexicans are extremely good at making light of life and light of themselves. My husband will be the first to tell you "Mexican jokes." He loves them, thinks they are hilarious. Instead of getting offended he just laughs. What a great way to go about life, no?
