hello, argentinian here, no
I'm not argentinian but I do know this is a well known argentinian sports comentator called Martin Lieberman, but I do not get the meme either

All the things mentioned in the replies have, for the general public, some sort of jinxing attribute. (Jinx = someone or something that will generate bad luck when bringing it up.) As it's usual, there's way more people using it for memes than actually believing on that kind of stuff.
