look up any word, like fleek:
 
1.
An artist that quickly become famous from a song they create that is very popular (They've always been there, but everyone is just discovering how good they are now)
Everyone: "Where did Icona Pop come from? they're so good!"

Some Hipster: "You're so late, i've been listening to them for years, they're just another breakout artist, you've probably only heard "I Don't Care" psh basic."
