These are two of my buddies Moose (the one in red) and Mario (the one in blue being . . dry humped?) and this pic is titled "Frios Frijoles "
I am posting this pic on a bet that has nothing to do with the picture or where it was taken. If you really must know, I will share the story with you elsewhere.
As I've said before, the more obscure the joke, the funnier it is.
