The closest phrase used here is "you rock", which is a complement meaning someone is very good at what they do

"You rock" is a fairly out dated phrase. Not many young people use this phrase anymore and I would find it strange if someone said it to me." Instead, a good modern alternative is the classic: "You're the best!" You would use the phrase when someone does something good for the other person and the recipient is thankful for the gesture.

Thanks for answer! You rock :-) I made mistake with this "are" , my bad. :-)

I have absolutely no idea. We do say: You rock! Meaning, you've done a great job. Or you really helped me on something, or you will do for me a really big favor.
