if you want to say “shut up” in greek you say “skase” which is basically a command to blow yourself up. im pretty sure the idea is like, “hold in your words for so long that they build up inside you until you burst” but it doesnt translate well. because the other day my cousin was practicing english convos with me, and when i was poking fun at her she just says “Explode.”
it translates as more of a power move than saying “shut up” normally though
