When you take into account it means "Laughing out loud" one could take it that Kasp is laughing at them for losing. You should have put more context, like "lol, haven't had a crazy game like this in a long time!".
Most likely it was a misunderstanding between the 2 players.
Watching the first turn I was assuming it was someone that didn't understand multiattack, but after the whole game, it might be that you didn't manage to eliminate them on turn 8.
