How well do you know your texting slang?
FCFS means whoever arrives or acts first gets the opportunity before anyone else. You will commonly see the acronym in retail, online shopping, and event ticketing, especially when a limited quantity of items is available.
For example, a store might announce a big sale with, "Discounted TVs—FCFS!" letting customers know that only the fastest shoppers will secure the deal. The phrase itself has been around for centuries as a simple way to describe fair, time-based distribution, but the acronym has become more popular in digital spaces where space and time are limited.
People often use "FCFS" in online listings, giveaways, and flash sales to indicate urgency and prevent debates over who gets what. You might see it in social media posts, classified ads, or group chats where someone offers a free item, as in, "Giving away concert tickets, FCFS!" The FCFS acronym clarifies that the first person to respond gets the tickets—no reservations, no holding.
