What is the slang meaning of the word 'yuo'?
According to several slang websites, there are no meaning to the word "Yuo". However, it is an alternative meaning of "You" due to the lack of precision while typing.
I think it would depend on the meaning of the word. Does the slang have a hateful or derogatory meaning, or is it a slur? If so, then no. If it has no hateful or derogatory connotations, then there's nothing wrong with it. Technnically speaking the word 'OK' is slang and nobody gets upset about that.
