5 Million Snowballs was an achievement in the Holiday Event 2015. This achievement also came back the the 2016 Winter Event. It is obtained by doing 600 races in a session with a holiday car. If you did one more race to get to 601 session races in this session you would earn the secret title "Frozen".
It is a rare title to see, and if you do see it, that racer is one of the few elites.
