A common misspelling of fursona (furry persona, a furry/animal character that represents yourself), for some reason. Mostly used by animal artists or animal character hoarders on sites like DeviantArt or ChickenSmoothie. Mostly teenage girls with emo wolf fursonas.

When you get a little piece of your meal stuck in your back teeth and you don't find it until later where you get to enjoy your food once again!
"I have some furosha stuck in my teeth. It tastes just as good as last time!"
