Obama = Buena Onda

In Buenos Aires, saying an individual is "buena onda" is perhaps one of the highest compliments you can give.  Literally, it means "good wave," but it's kind of like saying you get good vibes from someone (or something or someplace).  

Basically, you don't want to be friends with anyone unless they are muy buena onda, you don't want to hire anyone unless they are muy buena onda, and you don't want to date anyone unless they are muy buena onda. And clearly, you don't want to elect a president unless he's muy buena onda!

The above means:

Good day 

Buenos Aires

Vote Obama

BUENA ONDA!

Note: I asked this lady before taking a picture of her chest. She did not mind.
