Mother of Death - In the film Insidious: Chapter 2 (2013), during a seance scene, the question "What does she want?" is asked. Fifteen dice (with letters on each side) are then rolled out on to a table. The dice spring to life and spell out "mater mortis" - Latin for "mother of death."

DCs #1 school for sports... and posers. This school has more tools than a home depot! The kids there r OBSESSED with their school (and themselves). Yes... theyre good at sports but theyr also good at being insensitive douche bags. They hate any other DC school and ANY other definition of mater dei on this site that is sayin good things was written by a mater dei kid (or some dumb blonde from some public school).
Mater Dei Kid- Im sooooooo awesome!!! LAAAAAX!!!!
Dumb-Ass Blonde- Hhaha! I knoooow!!!! i sweat u!!!
Normal Kid: Not really.

A school in Santa Ana, California that is ridiculously good at sports. IT also provides a great education to those that want it. Also unlike that gay school called Sage Hill it does not cost 19 grand a year and there are not as many stuck up bitches that get escalades and porsches for their first cars.
