You

Vocative
/jou/
You is a typical Muxian slang that is used instead of dude (in spanish “tío” or “amigo”). This word is not common in writing but speech, specially in teens.

The time when this word was created is not clear, but lots of people think it comes from a 2014 party.
Definitely, you could use it in several situations, like when you want the salt “Can you hand me the salt, you?” or when you want to make a joint “You, do you want to make a joint?”

Eh you faime caso
“Hey dude, pay attention to me”
