ff vs ff15
The timing. "ff" asks to surrender now; "ff15" announces a surrender at fifteen minutes, the first moment it is possible. The second is almost always tilt.
ff
"ff" is short for forfeit: starting or calling for a surrender vote. At any point in the game, as soon as it is allowed, with a real assessment behind it: "ff we cant win this". Four votes out of five are enough.

"ff15" is a prediction, often typed at five minutes by a player who has decided the game is lost. It triggers nothing: the vote does not exist before fifteen minutes. It is a mood signal, not a team decision.

They look alike and answer each other: "ff15" at five, "ff" at fifteen. But an early "ff15" is far more dangerous than a late "ff", because it announces a player who stopped playing ten minutes before they could leave. The reply that works best: "dont ff we can win", and keep playing.
