The Boomerang is a weapon from the Balkon's Weapon Mod, which has the unique ability of returning to where it was thrown, unless it hits a mob or block in its path. Right-clicking charges the throw, and letting go releases the Boomerang.
While throwing the boomerang, it is strongly advised to be careful. Because the Boomerang returns to the spot it was thrown, running into its line of fire may result in the player dying. It is recommended to stand still while throwing.
Easy Boomerang Mode can be enabled in the config file of Balkon's Weapon Mod. Once this option is enabled, the boomerang returns to the player instead of the position it was thrown from.
