Cooties (2014) rated R for horror violence and gore, language including sexual references, and some drug use

A small group of teachers and students struggle to survive against other students when a mysterious illness aka "Cooties" breaks out and seems to rapidly infect every child that comes in contact with it.  It's a horror comedy zombie movie.  This film stars Elijah Wood, Rainn Wilson (Dwight from the American version of The Office), Alison Pill, and others.  It is a cute and slightly gross movie that will make you think twice about chicken nuggets.  The opening sequence is gross but once you get to Elijah Wood, you're pretty much in the clear.
