Slang...
Now I know some of you are TOTALLY 100 percent against it...
BUT....
I think everyone should have some understanding of it... sooo......
Here we go. some have other meanings, but these are the ones I hear most... none are offensive.
¿qué pedo? ¿qué onda? those mean whats up.
guey is a word you would call your friends... like in english we say dude, or homie, or bro.
órale, simón mean okay... or está bien
¡ándale! means c´mon, hurry up...
and ¡guácala! means yuck, or gross... like when you smell a babies dirty diaper or something like that...
what do you guys have¿?

I personally use British slang (I live in England) when I speak to the right people at the right places at the right times. The rest of the time, I try to speak standard English.
The problem with slang is that you need to know when and where to use it, and there is no guarantee that you'll be using it right or that it is in use where you are. Standard Spanish, on the other hand, is what parents normally use to talk to you, it is what you learn at school, and it is the main one used in newspapers, magazines and books. Learning slang is a good thing if you live in a place and you want to sound like they do; anyone will appreciate this. But it is not the right thing to do if you learn it from books or fora, because your communication will be hindered unless you know exactly what you're doingl. Besides, slang can be very expressive in many daily situations, but the range of things that you can express using slang is very limiting, if that's all you've got.
Anyway, try to apply for a job or do something serious using cool teenager slang, and see how far you get. Use the wrong slang, and you'll offend someone at some point if you are not careful.
Slang? Yes, sure, but only where it is used by natives, and not before standard Spanish.
However, you might bear in mind that in 5-10 years 99% of standard English/Spanish/Chinese/whatever will still be standard, while 50% of the now popular slang will have been replaced by newer slang (and the slang that you're learning now will be "square" [to use a slang term from the '50s/'60s]). If you move to another country (and in many cases, a different city in the same country), much of the slang will be different while the standard language will be the same.
I know a really great book that covers slang in Spanish. It denotes what country each slang word or term is used it, which is nice. Anyway it's called "Streetwise Spanish Dictionary and Thesaurus- The User Friendly Guide to Spanish Slang and Idioms" It is really helpful, and all of the one's you listed above can be found in the book. It costs about $15 but it's totally worth it.
(U can find it at Barnes & Nobles)
NO swearing on this forum, Nikkis.

Okay... some people here are annoying...
And missing the frickin point. Do you have anything better to do than to make things difficult?????
Why the hell do you need to know all the details..... I said i learned from various people in the states. I put those words up so you could recognize them if someone else used them. That is all...
This post was to inform ppl of what I know and to have them post words that they have heard or used.
Yeah I know... there is a lot of cussing...
well I only put things up there that I hear and that are used often...
I´m not saying anyone has to speak like that...just its good to know if you meet someone who does.
I didn't tell you, or anyone on that matter to use slang
What I said was I was telling you some common (I forgot to say Mexican)words. I thought people should know them, not necessarily use them. Just incase they were speaking with someone who uses that kind of speach. I am starting to think some of you are blind. You miss the point and make a big deal out of nothing.
All the slang that I mentioned is Mexican slang. I made many friends that were from Mexico when I lived in the states. My boyfriend, depending on who he is talking with, will speak like that too. I am not any frickin expert, but I mean I know some of the more common words.
'Nuff Said. 
@Incógnito- Are you challenging me or something? :
Slang is a part of language and culture but, if you tell someone that órale means something, don't you need to tell them where (country, city, etc) it's used? I know Spanish speaking people at work and none of them know what órale means so, I couldn't use it when speaking with them in Spanish. So, just knowing the word and what it means is only part of the meaning. So this site is to learn Spanish first and there are times where slang questions are asked and answered. By the way Nikkis, since you live in Mexico what does "Ella está hablaba en otra idoma....concas de su paíz" mean?
I have a file that lists about 5500 English slang words / expressions with explanations. I can send it to anyone wants it. None of it is translated to Spanish.
I think it's great to learn these things. If that's the way people really communicate, then it doesn't make sense to not learn about it.
That's what's wrong with a lot of our US Spanish classes. We would never cuss in a class, but cussing is a lot more prevalent in spanish culture.
I saw recently on Fox Sports where the coach of the Mexican soccer team said they were muy jodido. I nearly fell off my chair! Later Fox changed the headline on the main page, but left it as the headline of the story. And that really is what the coach said.
and I know metalero is a metalhead...
and once someone called me something like rockalera... or something like that? is that correct...like a rocker.
Slang isn't bad per se, but we all use slang in one way or another. but the most important thing is to know what people are saying...if i drop and f bomb, you know what i'm say, that i'm irritated and this or that thing is vaina to me. you don't have to use it. but you really do have to understand it.
