when you're totally out of it and everything goes ok, ignorance is bliss, haphazard behavior combined with a tendency towards klutziness...refers to the cartoon character Mr. Magoo
An exclamatory used in a situation in which you cannot find words to express the current state of being.
Used also in dire situations in which sentences cannot be formed quickly enough to convey your thoughts.
Used also in cases where thoughts are irrevocably passing through your mind vis-a-vis random instances; ergo you are forced to salvo in a tumultuous manner, "MAGOO!"
