Y/N 

A term usually used in fanfictions like ____ x reader. Y/N means "Your Name". So you would replace y/n for your name.

So lets say the sentence was

Jackson (yes wang): oh hey y/n, wanna come to my party this weekend?
Y/N: yeah sure!

You would read (ima use Emily for example)

Jackson (yes wang): oh hey Emily, wanna come to my party this weekend?
Emily: yeah sure!
