A retarded mmo released by gpotato. Mainly played by little kids, desperate teenagers, and pedophiles. The in-game avatars look like anime five year olds. One of the main features of the game is matchmaking, It matches you up for "dates" where lonely desperate men meet lonely desperate men pretending to be girls.
