The art of drilling a hole in your Girlfriends spine and ejaculating on the vertebrae to form an unbreakable bond what can never be broken.
Girlfriend : I'm leaving you for an African

Boyfriend : No way bitch your vertebrae is mine forever we made a bond so suck my penny whistle!

Girlfriend : You win lets fuck each others knee caps.

Spinal Branding is for life, not for African's...
