"youse" is in common usage in Australia when talking to more than one "you".
I don't have much of an issue with people saying "I am sat here, crying" as opposed to "I am sitting here" - possibly because the "I am sat here" is more of a description and not as relevant or active as the "crying" part of the phrase. I used to know more of the correct grammatical terminology to make more of an argument supporting why I don't particularly disagree with this usage (but it being quite commonly said where my Dad was brought up might have something to do with it, familiarity of usage makes it more acceptable)
However - use "loose" instead of "lose" and I will take your head off at the shoulders!
