Suggestion for a word to cheer with
 

I have a website that targets local residents. It is in English, but my area is about 20% Hispanic so I would like to build a similar one to target the Spanish speaking locals.

In order of population, the demographic is Mexican, Guatemalan, Honduran, and Salvadorian. I say this because I understand there are some dialect differences between them.

What I need is a cheering type of word that would be similar to "go", "yay", "woohoo", etc. Preferably a very short word that would be easy to recognize and remember.

A usage example might be, using my username, "Go dude!!"

I'm not sure if "Vamos dude!" conveys the same message.

Would "Ole dude" (without the accent) make sense?

Other suggestions?

We're not a translation site, but words like Yay! are interjections that can vary from country to country, and may not be equally understood by all people in the same country.
I suggest you not try to include the English word 'dude' when you're cheering someone on, as its equivalent in Spanish would often depend on the gender of the individual.

Safe words to use are:
¡Bien!
¡Bueno!
¡Buenísimo!
¡Órale! (El Salvador, Guatemala, Honduras, Mexico)
¡Epa! (El Salvador, Mexico)
¡Guau!

Note that an accent mark is important to include, should you choose an interjection that contains one.
