F/A/S/T
A stupid way to say "I want to trade or sell this". Like when you're in a paintball war and you’re too lazy to actually talk to someone, so you just spam F/A/S/T in the comments.
"F/A/S/T. This mask is worth 5000 points."
"F/A/S/T. I’ll trade you my green laser for your purple one."
"F/A/S/T. I’m selling my hat. It’s pink and it has glitter."
