I really think Lazaro is being unjustly and unkindly treated. I stand by the thought that it's a language thing.
I think someone told him to say it ... and he didn't know what it meant. People do that as a "joke" with people who don't know the language well ... that is, tell them to say a word and it ends up being a dirty or inappropriate word. I'm telling you that it was a mistake and/or unknowing ... and without intent to be disrespectful. I can't imagine why anyone would think he knowinglywould BE disrespectful to Randy. Incidentally ... you can hear Randy laughing in the background so apparently he was not offended in any way.
