A grammatically incorrect phrase used as the second line of an internet conversation. It originated as dialect from the Shropshire area of England but has become more widespread over the past 10 years. How's you is an abbreviated version of "how is you". This is how a poorly educated person would ask "How are you"
Person 1: Hello.
Person 2: hi
Person 1: How's you
Person 2: I am still capable of forming grammatically correct sentences. How are you?
