old hat

From old + hat, possibly a reference to something familiar and well-used. The Oxford English Dictionary suggests a connection to German alter Hut (“something familiar and hackneyed”, noun, literally “old hat”).

• "[Noël] Coward is such an old hand at this kind of thing that he makes it seem old hat."
• "In fact, monorails are rather old hat."
• "[I]t is old hat for a sex scandal to bring down a politician."
• "As for the greeting she [Elizabeth II] and her husband, Prince Philip, Duke of Edinburgh, received when they arrived outside the Capitol about 3:30 p.m. – well, based on the size of the crowd, perhaps the queen is old hat."
• "The only real knock against "Mortshall" is that "Rick and Morty get sick of each other and split up for a while" feels kind of old hat at this point—the comic premise of the show requires their relationship to be toxic (because a lot of the humor comes from seeing Rick be a shit and seeing Morty try haplessly to deal with Rick being a shit), and they can only try and sell the illusion that anything is going to change so many times before it starts to get stale."
