Here's a step by step guide to ripping open a coconut with your bear teeth, and that's bear teeth not bare teeth. Like the chompers of Chief Kap Te'o-Tafiti, a guy from the Polynesian Cultural Center in Hawaii who apparently flosses with steel.
Step 1: Just do it, you baby.
That's it. There are no more steps. Just do it because you're a man and you live that life.
Then just remember not to slice your ear off when you're cutting open the hard part of the coconut for the milk. Good luck on your journey.
