🧠 What Does FCFS Mean in Text?

In texting or online posts, it means priority goes to the first person who responds, shows up, or claims something. Once the item, spot, or opportunity is taken, it’s gone.

This slang is super common in online selling, giveaways, meetups, and sign-ups.

Example sentence:
“Selling my keyboard, $20. FCFS!”
