Soundies

Slang for people who work with sound on film sets and in film production. The lighting counterparts are lampies.

Your batteries died and you forgot to bring extras? Maybe you could score some from the soundies.

Sundies

A way to describe your sunglasses when you’re too lazy to write or say the entire word.

Just bought a fresh pair of Sundies to take to the beach with me. That sun won’t phase me.
