"youse" (its proper spelling), is derived from the Tri-State area slang language. Usually utilized by an overbearing uneducated race called "Guidos", it entails two people being spoken to directly.you don't see this on forums too much, but I hear it alot:
"Did yous (talking to 2 people) miss the bus?"
"Yous" is not plural for "you", lol.
"you" can be plural or singular.
it's supposed to be "Did you two miss the bus?"
For example, "What the fuck is wrong witch youse?!"
