When an "influencer" (usually Instagramwhite girls/fuck boys) posts a picture of the place they're at that includes some body of water that looks very blue, and very beautiful. Fact: this phrase was invented by Cody Ko, in his video titled "QUIT YOUR JOB AND TRAVEL FOREVER!!".
Person 1: "Look at this hot girl's Instagram post. 2 weeks in Greece! I wish I was her."
Person 2: "Yeah look at that blue ass water. Now I feel like shit."
