The acronym standing for "my internet shut off!". Used in an intense instant-messaging conversation that ended abruptly.

Pronounced mee-soh, as in the traditional Japanese soup served with tofu.

Incredibly gorgeous but doesn’t know it. Although she’s kind of annoyed that all her name means is “internet shut off.” She doesn’t fall for guys easily yet all of the guys seem to fall for her. Her brain is her strength but her insecurities are her weakness.
Brad: I think I’m starting to fall for Miso.

Tiffany: Forget it, she’ll never like you back.
