Translating from Germain litterally as "Oh my God!". Note the backthroat sound in ‘ach’, same as in ‘ich’, ‘Loch Ness Monster’, and similar to ‘Chanukah’(note the 'C'). Like 'Kahnukah' though without the full 'K'..
The most epic (zombie apocalypse expert) former teacher ever. With his Mr. Tumnus - like beard and his stories, Mr. Gott never failed to make anybody laugh in his (zombie apocalypse weapon hub) classroom.
Zombies: AAAAAAAH... Brains
Mr. Gott: AAAAAAH... I kill you now, you undead flesh addicts
Very common greeting in Austria and Bavaria loosely translated into "good day" having Catholic origins. Despite declining church attendance / affiliation, it's not unusual in those regions to hear it from an immigration/customs officer, a train conductor or even a McDonald's employee.

Food stand employee: Grüß Gott!
Customer: Ich hätte gerne einen Hot Dog und einen Krügel Bier. (I would like a hot dog and a pint of beer)
