look up any word, like wyd:
An elite private school in St. Paul MN. It is hard to get into, and even harder to graduate with a 3.5 or higher. Amazing sports, hot girls, and a lot of prep. The only negative is the uniforms. Often called CDH. Rival teams are Eden Prarie, Edina, and Mounds View.
I wish I could have gotten into Cretin-Derham Hall, but I get bad grades so I go to DeLaSalle.

Wow, look at that girl! She must go to Cretin-Derham Hall.
