For a bit of context, this is a reference to a 2014 Counter Strike major tournament where the team Fnatic used an unknown boost to get an unfair advantage over the other team. From their spawn point, they were able to use 3 different players to get a view over half of the map, allowing the pro player Olofmeister to snipe them unawares. They were 13 points down and about to be knocked out of the tournament, but the boost allowed them to win the game and (theoretically) move onto the semi finals. The other team had been using less powerful boost positions against them earlier in the game, and there weren’t hard rules against using such strategies, so they felt comfortable using it.

However, the outcry from across the esports world was enough for them to forfeit the match, allowing the other team, LDLC, to progress and eventually win the tournament. It has thus become an iconic moment in esports that shaped both professional standards and Counter Strike map design going forward.
