This zombie comedy movie I watched had a bunch of high school or maybe college students as the protagonists.
They go to a shop that sells occult items. One of them accidentally knocks over an urn or some other fragile object, which causes it to shatter. The shopkeeper warns them that they have just unleashed an evil force, and that anything they say in the shop will come true. The students then jokingly wish that, whenever they make eye contact with someone after midnight, that person will commit suicide and then reanimate as a zombie. Another one wishes that the zombies could be made to obey one of them by making out with them. I think the others also make some wishes.
Later on, one of the students is playing at a football game and makes contact with an opponent, triggering a zombie outbreak. Another student's mother commits suicide by electrocuting herself in a bathtub via a toaster.
I think they figure out that, in order to stop the outbreak, they need to perform some kind of ritual or maybe gather some items. They end up succeeding.
