grandfather hair 

A man’s longest pubic hair, the one that started to grow in first. For girls, this would be their grandmother hair.

Traditionally cut off and eaten in a last meal in specific First Nations culture, in soup or stew to celebrate the growth and life of the individual. In First Nations culture they call it Igrabaara (longevity follicle).

Example 1

Girl: Let’s get freaky tonight, babe!
Boy: Then you’ve gotta bite off my grandfather hair!
Girl: Yes, daddy! I’ll do anything you say!

Example 2

Our grandpa, Ikiiolio, is celebrating his final hours tonight, and is having his Igrabaara stew for dinner, as part of tradition.

Me: Something like you go back in time and kill your grandfather so that you won’t exist in time.
