Yes, that is your spine tingling.
Joik (aka yoik and jojk), is a cultural tradition from the Sámi people.
The Sámi joik to honor someone or something in their lives. It's not what you would traditionally call a "song" but instead is an expression of the essence of something. You can joik the wind, a friend, your family and more.

The Sámi live in the Northernmost sections of Norway, Sweden, Finland, and Russia.
For centuries, Joiking was outlawed when Nordic countries attempted to Christianize the Sámi. Today, however, the Sámi have regained many of their rights.
