y/a 

y/a is "Your age". I have been trying to search it but no one defined it 😅. Usually, a writer of fanfiction sometimes includes the reader in the story, making it second-person POV. Here's some examples:

Person 1: Hey y/n, you're y/a years old right?
Y/N (Y/N stand for "Your Name", also is usually used by a writer of fanfiction): Yes!

Y.A.

You're Amazing, contracted to Y.A. Said in response to someone bragging about themselves. Usually with a heavy dose of sarcasm.

Person 1: "I've been going to the gym 5 times a week, I'm really in the best shape I've ever been in"

Person 2: "oh, Y.A.... Y fricking A"

Y.A.L.A. 

You Always Live Again.

M.I.A.'s response to Y.O.L.O., based on her Eastern cultural heritage. In Hinduism it is believed that people are continuously reincarnated, so it's acceptable to do something more than once.

Also a title of a song on her 2013 album Matangi.

"Why does everyone keep saying Y.O.L.O. and then doing the same stupid stuff? It's such a waste."

"Yeah, back where I come from we say Y.A.L.A. before we do stupid stuff cuz we know we're not wasting any time in this life. But then they invented karma to make us feel bad."

Y.A.S.A.P 

If you want to tell a friend to watch a video or listen to a song via 'youtube', then instead of asking them to do it A.S.A.P or go-and-watch-that-video-now, you simply say Y.A.S.A.P (youtube that A.S.A.P).

John: Have you heard that Kendrick Lamar song 'Ignorance is bliss'?

Sam: Ahh, nah man I aint even heard it yet

John: Y.A.S.A.P
