Translation - Greek-English - Ναι, κορόιδευε εσύ! Τώρα που θα ρθει ...

Easter should not have "the" in front of it. Also, is this an expression in Greece? It doesn't make sense in English.

Hi Kafetzou,

No, it's not an expression, "the body" must be a nickname or smt.

I agree about the "the" in front of Easter, but the body is correct. It may don't make sense in English, but since you are probably Greek, too, Kafetzou, I think you got the point and how it is used in this sentence.
User10, "the body" is used as a nickname for someone who either looks like a dead body or someone who acts like one, meaning someone without energy, lifeless.

Suggestion that might be proposed as alternative meaning: "Now that Easter's coming, let's see how you'll feel when you'll see the dead corpse turning on the (roast) spit." I believe here the corpse is referring to the dead lamb being roasted, as per Greek tradition for Easter. Of course, it could also be a nasty reference to some relative, in which case sentence end would indeed be: "when you'll see the body / corpse return."

Majax, this is a version that didn't cross my mind, thank you! Though, as it isn't clear in the sentence, maybe nighta0508 could specify to what the "το πτώμα" refers.

nighta, is that possible? Could you provide us with more context? Otherwise, we will have to accept one of them and add the other as note.
