I go to church, do youth group, and run a bible study. I guess you could say that I'm a Cathaholic.

2.
Refers to a person of Catholic religion who is so addicted to this particular religion that they follow blindly everything the church or a priest says. These are the type of people who pray for every last thing to God. Wake up people, he doesn't care if you football team wins!!
My parents are such Cathaholics, they believe that the universe was created 2700 years ago. All that science stuff is the devil trying to sway our beliefs. Stupid science.
