The phrase is a colloquial German shortening of Das gibt eine Anzeige, meaning that will result in a police report. Online it circulated as a reaction sound on German soundboards, often misspelled as Anzeije to mimic the drawn out pronunciation. Tags linking it to knights and laughter reflect how it is shared as a joke threat rather than a serious clip. It remains popular in edits and chats because the meaning is clear even out of context and the short length fits quick punchlines.
