"Jerries" was a shortened form for "Germans" used by the allied soldiers during world war II. They used it because it was shorter and easier to say. Because you can't really say "Gers", the allies were saying "Jerries". There is no offensive or subliminal meaning on that word (unlike for "Krauts").
Getting white girl wasted and going on an adventure. May include blow up dolls, loodles, setting up the henty field days, posting seedy locanto adds or sexting a pic of your knee crease

A shortened form of "Germans" that wasn't really any shorter but was a bit easier to say. You can't really say "Gers" so it became "Jerries". Not necessarily a racial slur, but Germans may take offense to this.
