Definition
An green bird that owns the language learning website Duolingo. If you do not take your lessons you will get a message from Duolingo saying “Spanish or Vanish.” If you don’t take your lessons in the next 0.099999 seconds you will never be seen again. Believe it or not, there are actually 20 Duolingos. 5 of them have been killed. If you see this green bird (for images look up Duolingo and go to images), kill it or run. These Duolingo birds are also taking black and white forms (looks the same but is in black and white). Beware, and good luck.
