blood bind 

the combining of two or more person's blood to be close in some way.

The two friends decided they wanted to be best friends and took a needle and pressed their fingers together, creating their blood bind.

Bloody bindi 

When you bite a person's nipple off and spit it on to their forehead.

I lost my nip to the bloody bindi.

Bloodbending

From the show Avatar: The Last Airbender
A variation of waterbending in which a master waterbender utilizes the power of the full moon to control the water in the blood of all living things. Hama, a survivor of the Fire Nation raids on the Southern Water Tribe, developed the technique while being held prisoner in a Fire Nation cell. The prisoners were given no water, so Hama had to improvise. She spent years developing the technique and practiced on the rats that scurried across her cage. Finally, she used her new skill to break out, controlling the guard to use his key to open her cage.

Hama invented Bloodbending and taught it to Katara. Hopefully, Katara will utilize that power in the 3rd Season
