I am an extreme couponing type person.  Do you use coupons to save money routinely? 
I've never tried that, but I do really like the show as the whole concept is very interesting.
The term was coined by the Wall Street Journal in 2010.  They claimed it as a new extreme sport. 
Sport? So the goal is to buy as much products for as little money?
Exactly.  And then TLC and ABC channels both came out with shows showcasing extreme couponing.
