Thank goodness, I'm not alone in this thinking. It irritates me. I guess, ONE time after a kid was born is fine, but over and over again. It just looks absolutely ridiculous.
I find it quite an interesting goal celebration, although many of my friends hate it. I'm not sure it's only meaning is greeting the newborn baby. I think it's a gay provokation and it is meant to completely humiliate and sissify the opposition team and it's supporters: "I scored, so blow it!", or even worse: "I scored, you suck d*ck!" It's must be quite annoying for the opposition: Luis Garcia and David Villa also do it! I love it! The opposition supporters don't like to be called s*ssy f*ggots, and they are convinced that they are all macho pr*cks, but when D. Villa or Luis Garcia score against them, there sensational thumb-sucking gesture suggests exactly the opposite of their firm beliefs, doesn't it? The message of David Villa: "I can have any hot chick in the world, but you looser f*ggots blow!"
I'm a fan of this celebration, it basically means "f**k you," its an insult that is actually very old. In Shakespeare's Romeo and Juliet one of the characters even says "you bite your thumb at me" (this is a random memory from high school english, oh so long ago). The reference to it being tribute to his new born baby was released in the Diadora ad in Eurosport after the World Cup to defend against the true meaning of the gesture.
