A somewhat of a dead meme in Japan that you might hear a Japanese native say. It is often used when someone uses some fancy/obscure English or Japanese word that the listener doesn't know. Literally translated, it means "What is that? Is it delicious?". It has nothing to do with food though. 「Written in Japanese (with 漢字) -> 何それ?美味しいの?」
PS: Thank you Japanese Ammo with Misa

Every edgy highschooler ever: nani sore? oishii no?
An Oishi is a dreamer. They have wonderful smiles with the bestest dimples and are warm friends. Oishis are food and art connoisseurs and love to appreciate the simple things in life. Are insecure and have hearts that are a little fragile only because they are full of so much love to give. Oishis are witty and wild and can be found cursing computer scienceengineering projects at wee hours of the night.
