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?”
