Battle Kid 

A game that's so hard it should be illegal.

Playing this game is REALLY painful
You will die 1,000,000+ times

Battle Kid makes Dark Souls look like a game for babies

Battle Kid Episode 3 

The third episode in the Battle Kid Game Grumps series, in which one of the hosts, Arin Hanson, has various mental breakdowns due to being unable to beat a boss. In the end he quits the game by mistake. This phrase can be used when talking about a horrible experience.

Oh, it's Battle Kid Episode 3 all over again...
