Evil aliens have decided to kill everyone on Earth! Fortunately, they've given you two minutes to save as many as you can. All you have to do is name a country to save everyone in it.
Ofc those are the more common ways to refer to them but I'm always a fan of a neologism :) (and those aren't really specific words like the rest of this quiz). Seemingly nibling has existed since 1951 (and also auncle, should maybe accept that) but I must confess I don't think I've heard either one in natural speech, more just trivia than anything (for now at least)
