A Drakonir is a person who defeated a dragon and was by that once the strongest in the land.
It implies, that the person is brutally strong and cannot be defeated.
Person 1: Wow, have you seen Tom? He beat that guy really easy!
Person 2: Yes, he is so strong, he could be a Drakonir!
Someone who thinks she's a fashionista but in fact has nothing but a natural flair for not getting it (right/at all) and has a close resemblance to a dragon.
Friend 1: "Check out that girl wearing the BFpants with that oversized i (L) Paris t-shirt".
Friend 2: "I say "dragonista in the house!!!". So sad, you can just tell from the way she's standing there that she really thinks she's dressed to kill."
