Some Slang Used In Mexico
I don't know it all, but here are some of the slang words and uses I have picked up in Mexico. Some of them may actually used in other Latin American countries as well.

Güey- Probably the most used slang in Mexico. It is like "dude," and is used ALL the time (pronounced almost like “way”).
Pinche- fucking (adj.)
No manches- No way! Not to be used in formal situations.
No mames- No way! The cussword version. Definitely do not use this in formal situations. literally it basically means don't blow me.
Mamada- blow job
@- used when a word can be male or female, to represent both the “O” and the “A” in the word.

Hello all! My time in Mexico is winding down. I have only 3 months left on my contract, and then will be moving to NY where my fella lives. I have been thinking about what is on my "list"-- things I want to make sure I do before I leave. I was recently at a happy hour for NGO workers and environmentalists, and another gringa I chatted with mentioned that she was thinking about her list as well. I also recently had some visitors with whom I saw some of the basic sights again, and loved them just as much-- or more!-- than the first or second (or third) time(s).

A commercial for a skin-whitening lotion called White Secret has inspired some musings about race and skin color in Mexico. A few thoughts.

Hello again, from the biggest city in the world!* A few weekends ago, I went to a very fresa bar with some of my lawyer friends here (young feminist lawyers from the organization I work for). Fresa, in Mexico, means rich, snooty, haughty, etc. Literally, it means strawberry, and it is used to describe the upscale young people of which there are multitude in Mexico City. First clue: you have to buy a bottle to sit a table, and bottles were around US$130. WHAT!? Bottles of alcohols like Bacardi and Absolut cost about US$15 in the grocery stores here.

I recently got this trip idea from a Kayak.com email:
