Ill Eagle

Ill eagle means illegal. It is a term created by gamers that comes from the splitting of the two syllables that make up illegal.

Ill eagle was originally uttered by HelenaLive, a LoL streamer, who became upset when Arteezy (RTZ) trolled her by taking her name on Steam while playing DOTA. She declared that it was illegal but her Russian accent made it sound like she was saying "ill eagle." Because of her perceived fake reaction, which included crying, Twitch viewers began to mock her with ill eagle.
