It has three definitions:

1. Shorthand term for Thirty Times (when one say triple it means three times thus a Thriple is thirty times)

3. The name of the color in between the Red and the Magenta color spectrum. Lies more on the Violet / Purple side.

That is one unique thirple you got there man, damn.
