I still remember the first time someone texted me, “send the aux?” I stared at my screen, wondering if I was supposed to reply, Google it, or pretend I magically understood. Spoiler: I had no idea what “aux” meant.
If you’ve ever been in that moment confused, curious, and slightly panicked you’re definitely not alone. Slang evolves fast, and “aux” is one of those terms that shows up everywhere: texts, TikToks, parties, and captions.
Quick Answer:
“Aux” means “auxiliary,” and in texting or social media, it usually refers to the aux cord used to play music, or giving someone control of the playlist. It’s a casual, fun, social slang term.
🧠 What Does AUX Mean in Text?
In texting, “aux” is short for “auxiliary,” but the everyday meaning is far simpler:
👉 It refers to the aux cord or the ability to control the music.
When someone texts “pass the aux”, they’re saying:
🎵 “Let me control the music” or “You can play your songs now.”
Sometimes it’s also used metaphorically, like “who got aux today?”, meaning “who’s deciding the vibe or mood?” especially in group chats.
Example:
“u driving? ok cool, i got aux 😎”
In short: AUX = Auxiliary = Control of the music / playlist.
