How the clue works
Right, so "irritated" is your anagram flag, telling you to shuffle up get ogress — juggle those letters and you land on STGEORGES. Then just tack on CROSS, which is simply a synonym for "annoyed". Stick the two bits together and the whole thing is defined by symbol, pointing you at the St George's Cross emblem.
