The phrase "haddest it all over" is an archaic way of saying "you had it all under control". The spelling of "haddest" follows Old English conventions, with the "-est" affix denoting second person singular present tense. The word "over" is pronounced as /ˈəʊvər/ in IPA phonetic transcription, with the stress on the first syllable. The phrase can be traced back to the King James Version of the Bible and was a common expression in Shakespearean plays.
