"You are lying down already."
Translation:Te már fekszel.
It's not the most natural word order for this sentence, and there aren't many contexts where it would be used. It means something like: "now it's you who's lying". As if some people took turns in lying down. Or as if two people were wrestling, and one of them seemed stronger, but suddenly the other one knocked him to the ground: "You shouldn't be so arrogant anymore, már te fekszel."
