FY

"FY" is the abbreviation word for "For you ;)". It is used to show an unconditional and sincere appreciation for what someone just said to you by returning the same compliment. It always follows the word "Thank you for you".
Fun fact: "FY" is used a lot in Azerbaijan.

Pascal received presents from both of his friends during Christmas
Pascal: Oh wow, Christmas presents, thank you for you!
Julien: No, no, no, no, NO. Thank YOU for YOU.
Will: FY.
