With classic Killer Instinct online (SNES X-BAND videogame modem) it was called "pulling." "Pullers" would pull the phone cord out whem they were losing. The win was supposed to be awarded to the player who got best of three rounds and, IIRC, they patched it so that it would still award the wins and losses based on whoever was ahead/behind. All that did was make people pull when the tie was about to break or pull on the first round, so they patched it again to award the lead player the win and the losing player neither a loss nor a win. This prompted some people to game the system by pulling after winning the first round so that they could eliminate the chance of you catching up, win more matches faster, and climb the ranks easier. At first this would assign you the loss as if you pulled.
